Abstract
Description
- The present application claims the benefit of Indian Provisional Patent Application No. 201741030632, filed Aug. 30, 2017 and U.S. Provisional Patent Application No. 62/584,401, filed Nov. 10, 2017.
- In systems that distribute workloads among multiple compute devices (e.g., in a data center), a centralized server may compose nodes of compute devices to process the workloads. Each node represents a logical aggregation of resources (e.g., compute, storage, acceleration, and the like) provided by each compute device. For instance, the node may include a compute device configured with hardware accelerators, such as field-programmable gate array (FPGA) devices and/or graphical processing units (GPUs). Generally, the hardware accelerator improves the execution speed of workload functions. To accelerate a given function of a workload, such as of an application, the centralized server may configure an accelerator device with an accelerated kernel that is suitable for accelerating the task. Once complete, the accelerator device returns data resulting from the accelerated function to the application.

- Referring now to
FIG. 1 , adata center 100 in which disaggregated resources may cooperatively execute one or more workloads (e.g., applications on behalf of customers) includesmultiple pods pod spine switches 150 that switch communications among pods (e.g., thepods data center 100. In some embodiments, the sleds may be connected with a fabric using Intel Omni-Path technology. As described in more detail herein, resources within sleds in thedata center 100 may be allocated to a group (referred to herein as a “managed node”) containing resources from one or more other sleds to be collectively utilized in the execution of a workload. The workload can execute as if the resources belonging to the managed node were located on the same sled. The resources in a managed node may even belong to sleds belonging to different racks, and even todifferent pods data center 100 provides more efficient resource usage over typical data centers comprised of hyperconverged servers containing compute, memory, storage and perhaps additional resources). As such, thedata center 100 may provide greater performance (e.g., throughput, operations per second, latency, etc.) than a typical data center that has the same number of resources. - Referring now to
FIG. 2 , thepod 110, in the illustrative embodiment, includes a set ofrows racks 240. Eachrack 240 may house multiple sleds (e.g., sixteen sleds) and provide power and data connections to the housed sleds, as described in more detail herein. In the illustrative embodiment, the racks in eachrow pod switch 250 includes a set ofports 252 to which the sleds of the racks of thepod 110 are connected and another set ofports 254 that connect thepod 110 to the spine switches 150 to provide connectivity to other pods in thedata center 100. Similarly, thepod switch 260 includes a set ofports 262 to which the sleds of the racks of thepod 110 are connected and a set ofports 264 that connect thepod 110 to the spine switches 150. As such, the use of the pair ofswitches pod 110. For example, if either of theswitches pod 110 may still maintain data communication with the remainder of the data center 100 (e.g., sleds of other pods) through theother switch switches - It should be appreciated that each of the
other pods pod 110 shown in and described in regard toFIG. 2 (e.g., each pod may have rows of racks housing multiple sleds as described above). Additionally, while twopod switches pod - Referring now to
FIGS. 3-5 , eachillustrative rack 240 of thedata center 100 includes two elongated support posts 302, 304, which are arranged vertically. For example, the elongated support posts 302, 304 may extend upwardly from a floor of thedata center 100 when deployed. Therack 240 also includes one or morehorizontal pairs 310 of elongated support arms 312 (identified inFIG. 3 via a dashed ellipse) configured to support a sled of thedata center 100 as discussed below. Oneelongated support arm 312 of the pair ofelongated support arms 312 extends outwardly from theelongated support post 302 and the otherelongated support arm 312 extends outwardly from theelongated support post 304. - In the illustrative embodiments, each sled of the
data center 100 is embodied as a chassis-less sled. That is, each sled has a chassis-less circuit board substrate on which physical resources (e.g., processors, memory, accelerators, storage, etc.) are mounted as discussed in more detail below. As such, therack 240 is configured to receive the chassis-less sleds. For example, eachpair 310 ofelongated support arms 312 defines asled slot 320 of therack 240, which is configured to receive a corresponding chassis-less sled. To do so, each illustrativeelongated support arm 312 includes acircuit board guide 330 configured to receive the chassis-less circuit board substrate of the sled. Eachcircuit board guide 330 is secured to, or otherwise mounted to, atop side 332 of the correspondingelongated support arm 312. For example, in the illustrative embodiment, eachcircuit board guide 330 is mounted at a distal end of the correspondingelongated support arm 312 relative to the correspondingelongated support post circuit board guide 330 may be referenced in each Figure. - Each
circuit board guide 330 includes an inner wall that defines acircuit board slot 380 configured to receive the chassis-less circuit board substrate of asled 400 when thesled 400 is received in thecorresponding sled slot 320 of therack 240. To do so, as shown inFIG. 4 , a user (or robot) aligns the chassis-less circuit board substrate of anillustrative chassis-less sled 400 to asled slot 320. The user, or robot, may then slide the chassis-less circuit board substrate forward into thesled slot 320 such that eachside edge 414 of the chassis-less circuit board substrate is received in a correspondingcircuit board slot 380 of the circuit board guides 330 of thepair 310 ofelongated support arms 312 that define thecorresponding sled slot 320 as shown inFIG. 4 . By having robotically accessible and robotically manipulable sleds comprising disaggregated resources, each type of resource can be upgraded independently of each other and at their own optimized refresh rate. Furthermore, the sleds are configured to blindly mate with power and data communication cables in eachrack 240, enhancing their ability to be quickly removed, upgraded, reinstalled, and/or replaced. As such, in some embodiments, thedata center 100 may operate (e.g., execute workloads, undergo maintenance and/or upgrades, etc.) without human involvement on the data center floor. In other embodiments, a human may facilitate one or more maintenance or upgrade operations in thedata center 100. - It should be appreciated that each
circuit board guide 330 is dual sided. That is, eachcircuit board guide 330 includes an inner wall that defines acircuit board slot 380 on each side of thecircuit board guide 330. In this way, eachcircuit board guide 330 can support a chassis-less circuit board substrate on either side. As such, a single additional elongated support post may be added to therack 240 to turn therack 240 into a two-rack solution that can hold twice asmany sled slots 320 as shown inFIG. 3 . Theillustrative rack 240 includes sevenpairs 310 ofelongated support arms 312 that define a corresponding sevensled slots 320, each configured to receive and support acorresponding sled 400 as discussed above. Of course, in other embodiments, therack 240 may include additional orfewer pairs 310 of elongated support arms 312 (i.e., additional or fewer sled slots 320). It should be appreciated that because thesled 400 is chassis-less, thesled 400 may have an overall height that is different than typical servers. As such, in some embodiments, the height of eachsled slot 320 may be shorter than the height of a typical server (e.g., shorter than a single rank unit, “1 U”). That is, the vertical distance between eachpair 310 ofelongated support arms 312 may be less than a standard rack unit “1 U.” Additionally, due to the relative decrease in height of thesled slots 320, the overall height of therack 240 in some embodiments may be shorter than the height of traditional rack enclosures. For example, in some embodiments, each of the elongated support posts 302, 304 may have a length of six feet or less. Again, in other embodiments, therack 240 may have different dimensions. Further, it should be appreciated that therack 240 does not include any walls, enclosures, or the like. Rather, therack 240 is an enclosure-less rack that is opened to the local environment. Of course, in some cases, an end plate may be attached to one of the elongated support posts 302, 304 in those situations in which therack 240 forms an end-of-row rack in thedata center 100. - In some embodiments, various interconnects may be routed upwardly or downwardly through the elongated support posts 302, 304. To facilitate such routing, each
elongated support post sled slot 320, power interconnects to provide power to eachsled slot 320, and/or other types of interconnects. - The
rack 240, in the illustrative embodiment, includes a support platform on which a corresponding optical data connector (not shown) is mounted. Each optical data connector is associated with acorresponding sled slot 320 and is configured to mate with an optical data connector of acorresponding sled 400 when thesled 400 is received in thecorresponding sled slot 320. In some embodiments, optical connections between components (e.g., sleds, racks, and switches) in thedata center 100 are made with a blind mate optical connection. For example, a door on each cable may prevent dust from contaminating the fiber inside the cable. In the process of connecting to a blind mate optical connector mechanism, the door is pushed open when the end of the cable enters the connector mechanism. Subsequently, the optical fiber inside the cable enters a gel within the connector mechanism and the optical fiber of one cable comes into contact with the optical fiber of another cable within the gel inside the connector mechanism. - The
illustrative rack 240 also includes afan array 370 coupled to the cross-support arms of therack 240. Thefan array 370 includes one or more rows of coolingfans 372, which are aligned in a horizontal line between the elongated support posts 302, 304. In the illustrative embodiment, thefan array 370 includes a row of coolingfans 372 for eachsled slot 320 of therack 240. As discussed above, eachsled 400 does not include any on-board cooling system in the illustrative embodiment and, as such, thefan array 370 provides cooling for eachsled 400 received in therack 240. Eachrack 240, in the illustrative embodiment, also includes a power supply associated with eachsled slot 320. Each power supply is secured to one of theelongated support arms 312 of thepair 310 ofelongated support arms 312 that define thecorresponding sled slot 320. For example, therack 240 may include a power supply coupled or secured to eachelongated support arm 312 extending from theelongated support post 302. Each power supply includes a power connector configured to mate with a power connector of thesled 400 when thesled 400 is received in thecorresponding sled slot 320. In the illustrative embodiment, thesled 400 does not include any on-board power supply and, as such, the power supplies provided in therack 240 supply power to correspondingsleds 400 when mounted to therack 240. - Referring now to
FIG. 6 , thesled 400, in the illustrative embodiment, is configured to be mounted in acorresponding rack 240 of thedata center 100 as discussed above. In some embodiments, eachsled 400 may be optimized or otherwise configured for performing particular tasks, such as compute tasks, acceleration tasks, data storage tasks, etc. For example, thesled 400 may be embodied as acompute sled 800 as discussed below in regard toFIGS. 8-9 , anaccelerator sled 1000 as discussed below in regard toFIGS. 10-11 , astorage sled 1200 as discussed below in regard toFIGS. 12-13 , or as a sled optimized or otherwise configured to perform other specialized tasks, such as amemory sled 1400, discussed below in regard toFIG. 14 . - As discussed above, the
illustrative sled 400 includes a chassis-lesscircuit board substrate 602, which supports various physical resources (e.g., electrical components) mounted thereon. It should be appreciated that thecircuit board substrate 602 is “chassis-less” in that thesled 400 does not include a housing or enclosure. Rather, the chassis-lesscircuit board substrate 602 is open to the local environment. The chassis-lesscircuit board substrate 602 may be formed from any material capable of supporting the various electrical components mounted thereon. For example, in an illustrative embodiment, the chassis-lesscircuit board substrate 602 is formed from an FR-4 glass-reinforced epoxy laminate material. Of course, other materials may be used to form the chassis-lesscircuit board substrate 602 in other embodiments. - As discussed in more detail below, the chassis-less
circuit board substrate 602 includes multiple features that improve the thermal cooling characteristics of the various electrical components mounted on the chassis-lesscircuit board substrate 602. As discussed, the chassis-lesscircuit board substrate 602 does not include a housing or enclosure, which may improve the airflow over the electrical components of thesled 400 by reducing those structures that may inhibit air flow. For example, because the chassis-lesscircuit board substrate 602 is not positioned in an individual housing or enclosure, there is no backplane (e.g., a backplate of the chassis) to the chassis-lesscircuit board substrate 602, which could inhibit air flow across the electrical components. Additionally, the chassis-lesscircuit board substrate 602 has a geometric shape configured to reduce the length of the airflow path across the electrical components mounted to the chassis-lesscircuit board substrate 602. For example, the illustrative chassis-lesscircuit board substrate 602 has awidth 604 that is greater than adepth 606 of the chassis-lesscircuit board substrate 602. In one particular embodiment, for example, the chassis-lesscircuit board substrate 602 has a width of about 21 inches and a depth of about 9 inches, compared to a typical server that has a width of about 17 inches and a depth of about 39 inches. As such, anairflow path 608 that extends from afront edge 610 of the chassis-lesscircuit board substrate 602 toward arear edge 612 has a shorter distance relative to typical servers, which may improve the thermal cooling characteristics of thesled 400. Furthermore, although not illustrated inFIG. 6 , the various physical resources mounted to the chassis-lesscircuit board substrate 602 are mounted in corresponding locations such that no two substantively heat-producing electrical components shadow each other as discussed in more detail below. That is, no two electrical components, which produce appreciable heat during operation (i.e., greater than a nominal heat sufficient enough to adversely impact the cooling of another electrical component), are mounted to the chassis-lesscircuit board substrate 602 linearly in-line with each other along the direction of the airflow path 608 (i.e., along a direction extending from thefront edge 610 toward therear edge 612 of the chassis-less circuit board substrate 602). - As discussed above, the
illustrative sled 400 includes one or morephysical resources 620 mounted to atop side 650 of the chassis-lesscircuit board substrate 602. Although twophysical resources 620 are shown inFIG. 6 , it should be appreciated that thesled 400 may include one, two, or morephysical resources 620 in other embodiments. Thephysical resources 620 may be embodied as any type of processor, controller, or other compute circuit capable of performing various tasks such as compute functions and/or controlling the functions of thesled 400 depending on, for example, the type or intended functionality of thesled 400. For example, as discussed in more detail below, thephysical resources 620 may be embodied as high-performance processors in embodiments in which thesled 400 is embodied as a compute sled, as accelerator co-processors or circuits in embodiments in which thesled 400 is embodied as an accelerator sled, storage controllers in embodiments in which thesled 400 is embodied as a storage sled, or a set of memory devices in embodiments in which thesled 400 is embodied as a memory sled. - The
sled 400 also includes one or more additionalphysical resources 630 mounted to thetop side 650 of the chassis-lesscircuit board substrate 602. In the illustrative embodiment, the additional physical resources include a network interface controller (NIC) as discussed in more detail below. Of course, depending on the type and functionality of thesled 400, thephysical resources 630 may include additional or other electrical components, circuits, and/or devices in other embodiments. - The
physical resources 620 are communicatively coupled to thephysical resources 630 via an input/output (I/O)subsystem 622. The I/O subsystem 622 may be embodied as circuitry and/or components to facilitate input/output operations with thephysical resources 620, thephysical resources 630, and/or other components of thesled 400. For example, the I/O subsystem 622 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, integrated sensor hubs, firmware devices, communication links (e.g., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.), and/or other components and subsystems to facilitate the input/output operations. In the illustrative embodiment, the I/O subsystem 622 is embodied as, or otherwise includes, a double data rate 4 (DDR4) data bus or a DDR5 data bus. - In some embodiments, the
sled 400 may also include a resource-to-resource interconnect 624. The resource-to-resource interconnect 624 may be embodied as any type of communication interconnect capable of facilitating resource-to-resource communications. In the illustrative embodiment, the resource-to-resource interconnect 624 is embodied as a high-speed point-to-point interconnect (e.g., faster than the I/O subsystem 622). For example, the resource-to-resource interconnect 624 may be embodied as a QuickPath Interconnect (QPI), an UltraPath Interconnect (UPI), or other high-speed point-to-point interconnect dedicated to resource-to-resource communications. - The
sled 400 also includes apower connector 640 configured to mate with a corresponding power connector of therack 240 when thesled 400 is mounted in thecorresponding rack 240. Thesled 400 receives power from a power supply of therack 240 via thepower connector 640 to supply power to the various electrical components of thesled 400. That is, thesled 400 does not include any local power supply (i.e., an on-board power supply) to provide power to the electrical components of thesled 400. The exclusion of a local or on-board power supply facilitates the reduction in the overall footprint of the chassis-lesscircuit board substrate 602, which may increase the thermal cooling characteristics of the various electrical components mounted on the chassis-lesscircuit board substrate 602 as discussed above. In some embodiments, power is provided to theprocessors 820 through vias directly under the processors 820 (e.g., through thebottom side 750 of the chassis-less circuit board substrate 602), providing an increased thermal budget, additional current and/or voltage, and better voltage control over typical boards. - In some embodiments, the
sled 400 may also include mountingfeatures 642 configured to mate with a mounting arm, or other structure, of a robot to facilitate the placement of the sled 600 in arack 240 by the robot. The mounting features 642 may be embodied as any type of physical structures that allow the robot to grasp thesled 400 without damaging the chassis-lesscircuit board substrate 602 or the electrical components mounted thereto. For example, in some embodiments, the mounting features 642 may be embodied as non-conductive pads attached to the chassis-lesscircuit board substrate 602. In other embodiments, the mounting features may be embodied as brackets, braces, or other similar structures attached to the chassis-lesscircuit board substrate 602. The particular number, shape, size, and/or make-up of the mountingfeature 642 may depend on the design of the robot configured to manage thesled 400. - Referring now to
FIG. 7 , in addition to thephysical resources 630 mounted on thetop side 650 of the chassis-lesscircuit board substrate 602, thesled 400 also includes one ormore memory devices 720 mounted to abottom side 750 of the chassis-lesscircuit board substrate 602. That is, the chassis-lesscircuit board substrate 602 is embodied as a double-sided circuit board. Thephysical resources 620 are communicatively coupled to thememory devices 720 via the I/O subsystem 622. For example, thephysical resources 620 and thememory devices 720 may be communicatively coupled by one or more vias extending through the chassis-lesscircuit board substrate 602. Eachphysical resource 620 may be communicatively coupled to a different set of one ormore memory devices 720 in some embodiments. Alternatively, in other embodiments, eachphysical resource 620 may be communicatively coupled to eachmemory devices 720. - The
memory devices 720 may be embodied as any type of memory device capable of storing data for thephysical resources 620 during operation of thesled 400, such as any type of volatile (e.g., dynamic random access memory (DRAM), etc.) or non-volatile memory. Volatile memory may be a storage medium that requires power to maintain the state of data stored by the medium. Non-limiting examples of volatile memory may include various types of random access memory (RAM), such as dynamic random access memory (DRAM) or static random access memory (SRAM). One particular type of DRAM that may be used in a memory module is synchronous dynamic random access memory (SDRAM). In particular embodiments, DRAM of a memory component may comply with a standard promulgated by JEDEC, such as JESD79F for DDR SDRAM, JESD79-2F for DDR2 SDRAM, JESD79-3F for DDR3 SDRAM, JESD79-4A for DDR4 SDRAM, JESD209 for Low Power DDR (LPDDR), JESD209-2 for LPDDR2, JESD209-3 for LPDDR3, and JESD209-4 for LPDDR4 (these standards are available at www.jedec.org). Such standards (and similar standards) may be referred to as DDR-based standards and communication interfaces of the storage devices that implement such standards may be referred to as DDR-based interfaces. - In one embodiment, the memory device is a block addressable memory device, such as those based on NAND or NOR technologies. A memory device may also include next-generation nonvolatile devices, such as Intel 3D XPoint™ memory or other byte addressable write-in-place nonvolatile memory devices. In one embodiment, the memory device may be or may include memory devices that use chalcogenide glass, multi-threshold level NAND flash memory, NOR flash memory, single or multi-level Phase Change Memory (PCM), a resistive memory, nanowire memory, ferroelectric transistor random access memory (FeTRAM), anti-ferroelectric memory, magnetoresistive random access memory (MRAM) memory that incorporates memristor technology, resistive memory including the metal oxide base, the oxygen vacancy base and the conductive bridge Random Access Memory (CB-RAM), or spin transfer torque (STT)-MRAM, a spintronic magnetic junction memory based device, a magnetic tunneling junction (MTJ) based device, a DW (Domain Wall) and SOT (Spin Orbit Transfer) based device, a thyristor based memory device, or a combination of any of the above, or other memory. The memory device may refer to the die itself and/or to a packaged memory product. In some embodiments, the memory device may comprise a transistor-less stackable cross point architecture in which memory cells sit at the intersection of word lines and bit lines and are individually addressable and in which bit storage is based on a change in bulk resistance.

FIG. 8 , in some embodiments, thesled 400 may be embodied as acompute sled 800. Thecompute sled 800 is optimized, or otherwise configured, to perform compute tasks. Of course, as discussed above, thecompute sled 800 may rely on other sleds, such as acceleration sleds and/or storage sleds, to perform such compute tasks. Thecompute sled 800 includes various physical resources (e.g., electrical components) similar to the physical resources of thesled 400, which have been identified inFIG. 8 using the same reference numbers. The description of such components provided above in regard toFIGS. 6 and 7 applies to the corresponding components of thecompute sled 800 and is not repeated herein for clarity of the description of thecompute sled 800. - In the
illustrative compute sled 800, thephysical resources 620 are embodied asprocessors 820. Although only twoprocessors 820 are shown inFIG. 8 , it should be appreciated that thecompute sled 800 may includeadditional processors 820 in other embodiments. Illustratively, theprocessors 820 are embodied as high-performance processors 820 and may be configured to operate at a relatively high power rating. Although theprocessors 820 generate additional heat operating at power ratings greater than typical processors (which operate at around 155-230 W), the enhanced thermal cooling characteristics of the chassis-lesscircuit board substrate 602 discussed above facilitate the higher power operation. For example, in the illustrative embodiment, theprocessors 820 are configured to operate at a power rating of at least 250 W. In some embodiments, theprocessors 820 may be configured to operate at a power rating of at least 350 W. - In some embodiments, the
compute sled 800 may also include a processor-to-processor interconnect 842. Similar to the resource-to-resource interconnect 624 of thesled 400 discussed above, the processor-to-processor interconnect 842 may be embodied as any type of communication interconnect capable of facilitating processor-to-processor interconnect 842 communications. In the illustrative embodiment, the processor-to-processor interconnect 842 is embodied as a high-speed point-to-point interconnect (e.g., faster than the I/O subsystem 622). For example, the processor-to-processor interconnect 842 may be embodied as a QuickPath Interconnect (QPI), an UltraPath Interconnect (UPI), or other high-speed point-to-point interconnect dedicated to processor-to-processor communications. - The
compute sled 800 also includes acommunication circuit 830. Theillustrative communication circuit 830 includes a network interface controller (NIC) 832, which may also be referred to as a host fabric interface (HFI). TheNIC 832 may be embodied as, or otherwise include, any type of integrated circuit, discrete circuits, controller chips, chipsets, add-in-boards, daughtercards, network interface cards, other devices that may be used by thecompute sled 800 to connect with another compute device (e.g., with other sleds 400). In some embodiments, theNIC 832 may be embodied as part of a system-on-a-chip (SoC) that includes one or more processors, or included on a multichip package that also contains one or more processors. In some embodiments, theNIC 832 may include a local processor (not shown) and/or a local memory (not shown) that are both local to theNIC 832. In such embodiments, the local processor of theNIC 832 may be capable of performing one or more of the functions of theprocessors 820. Additionally or alternatively, in such embodiments, the local memory of theNIC 832 may be integrated into one or more components of the compute sled at the board level, socket level, chip level, and/or other levels. - The
communication circuit 830 is communicatively coupled to anoptical data connector 834. Theoptical data connector 834 is configured to mate with a corresponding optical data connector of therack 240 when thecompute sled 800 is mounted in therack 240. Illustratively, theoptical data connector 834 includes a plurality of optical fibers which lead from a mating surface of theoptical data connector 834 to anoptical transceiver 836. Theoptical transceiver 836 is configured to convert incoming optical signals from the rack-side optical data connector to electrical signals and to convert electrical signals to outgoing optical signals to the rack-side optical data connector. Although shown as forming part of theoptical data connector 834 in the illustrative embodiment, theoptical transceiver 836 may form a portion of thecommunication circuit 830 in other embodiments. - In some embodiments, the
compute sled 800 may also include anexpansion connector 840. In such embodiments, theexpansion connector 840 is configured to mate with a corresponding connector of an expansion chassis-less circuit board substrate to provide additional physical resources to thecompute sled 800. The additional physical resources may be used, for example, by theprocessors 820 during operation of thecompute sled 800. The expansion chassis-less circuit board substrate may be substantially similar to the chassis-lesscircuit board substrate 602 discussed above and may include various electrical components mounted thereto. The particular electrical components mounted to the expansion chassis-less circuit board substrate may depend on the intended functionality of the expansion chassis-less circuit board substrate. For example, the expansion chassis-less circuit board substrate may provide additional compute resources, memory resources, and/or storage resources. As such, the additional physical resources of the expansion chassis-less circuit board substrate may include, but is not limited to, processors, memory devices, storage devices, and/or accelerator circuits including, for example, field programmable gate arrays (FPGA), application-specific integrated circuits (ASICs), security co-processors, graphics processing units (GPUs), machine learning circuits, or other specialized processors, controllers, devices, and/or circuits. - Referring now to
FIG. 9 , an illustrative embodiment of thecompute sled 800 is shown. As shown, theprocessors 820,communication circuit 830, andoptical data connector 834 are mounted to thetop side 650 of the chassis-lesscircuit board substrate 602. Any suitable attachment or mounting technology may be used to mount the physical resources of thecompute sled 800 to the chassis-lesscircuit board substrate 602. For example, the various physical resources may be mounted in corresponding sockets (e.g., a processor socket), holders, or brackets. In some cases, some of the electrical components may be directly mounted to the chassis-lesscircuit board substrate 602 via soldering or similar techniques. - As discussed above, the
individual processors 820 andcommunication circuit 830 are mounted to thetop side 650 of the chassis-lesscircuit board substrate 602 such that no two heat-producing, electrical components shadow each other. In the illustrative embodiment, theprocessors 820 andcommunication circuit 830 are mounted in corresponding locations on thetop side 650 of the chassis-lesscircuit board substrate 602 such that no two of those physical resources are linearly in-line with others along the direction of theairflow path 608. It should be appreciated that, although theoptical data connector 834 is in-line with thecommunication circuit 830, theoptical data connector 834 produces no or nominal heat during operation. - The
memory devices 720 of thecompute sled 800 are mounted to thebottom side 750 of the of the chassis-lesscircuit board substrate 602 as discussed above in regard to thesled 400. Although mounted to thebottom side 750, thememory devices 720 are communicatively coupled to theprocessors 820 located on thetop side 650 via the I/O subsystem 622. Because the chassis-lesscircuit board substrate 602 is embodied as a double-sided circuit board, thememory devices 720 and theprocessors 820 may be communicatively coupled by one or more vias, connectors, or other mechanisms extending through the chassis-lesscircuit board substrate 602. Of course, eachprocessor 820 may be communicatively coupled to a different set of one ormore memory devices 720 in some embodiments. Alternatively, in other embodiments, eachprocessor 820 may be communicatively coupled to eachmemory device 720. In some embodiments, thememory devices 720 may be mounted to one or more memory mezzanines on the bottom side of the chassis-lesscircuit board substrate 602 and may interconnect with acorresponding processor 820 through a ball-grid array. - Each of the
processors 820 includes aheatsink 850 secured thereto. Due to the mounting of thememory devices 720 to thebottom side 750 of the chassis-less circuit board substrate 602 (as well as the vertical spacing of thesleds 400 in the corresponding rack 240), thetop side 650 of the chassis-lesscircuit board substrate 602 includes additional “free” area or space that facilitates the use ofheatsinks 850 having a larger size relative to traditional heatsinks used in typical servers. Additionally, due to the improved thermal cooling characteristics of the chassis-lesscircuit board substrate 602, none of theprocessor heatsinks 850 include cooling fans attached thereto. That is, each of theheatsinks 850 is embodied as a fan-less heatsinks. - Referring now to
FIG. 10 , in some embodiments, thesled 400 may be embodied as anaccelerator sled 1000. Theaccelerator sled 1000 is optimized, or otherwise configured, to perform specialized compute tasks, such as machine learning, encryption, hashing, or other computational-intensive task. In some embodiments, for example, acompute sled 800 may offload tasks to theaccelerator sled 1000 during operation. Theaccelerator sled 1000 includes various components similar to components of thesled 400 and/or computesled 800, which have been identified inFIG. 10 using the same reference numbers. The description of such components provided above in regard toFIGS. 6, 7, and 8 apply to the corresponding components of theaccelerator sled 1000 and is not repeated herein for clarity of the description of theaccelerator sled 1000. - In the
illustrative accelerator sled 1000, thephysical resources 620 are embodied asaccelerator circuits 1020. Although only twoaccelerator circuits 1020 are shown inFIG. 10 , it should be appreciated that theaccelerator sled 1000 may includeadditional accelerator circuits 1020 in other embodiments. For example, as shown inFIG. 11 , theaccelerator sled 1000 may include fouraccelerator circuits 1020 in some embodiments. Theaccelerator circuits 1020 may be embodied as any type of processor, co-processor, compute circuit, or other device capable of performing compute or processing operations. For example, theaccelerator circuits 1020 may be embodied as, for example, field programmable gate arrays (FPGA), application-specific integrated circuits (ASICs), security co-processors, graphics processing units (GPUs), machine learning circuits, or other specialized processors, controllers, devices, and/or circuits. - In some embodiments, the
accelerator sled 1000 may also include an accelerator-to-accelerator interconnect 1042. Similar to the resource-to-resource interconnect 624 of the sled 600 discussed above, the accelerator-to-accelerator interconnect 1042 may be embodied as any type of communication interconnect capable of facilitating accelerator-to-accelerator communications. In the illustrative embodiment, the accelerator-to-accelerator interconnect 1042 is embodied as a high-speed point-to-point interconnect (e.g., faster than the I/O subsystem 622). For example, the accelerator-to-accelerator interconnect 1042 may be embodied as a QuickPath Interconnect (QPI), an UltraPath Interconnect (UPI), or other high-speed point-to-point interconnect dedicated to processor-to-processor communications. In some embodiments, theaccelerator circuits 1020 may be daisy-chained with aprimary accelerator circuit 1020 connected to theNIC 832 andmemory 720 through the I/O subsystem 622 and asecondary accelerator circuit 1020 connected to theNIC 832 andmemory 720 through aprimary accelerator circuit 1020. - Referring now to
FIG. 11 , an illustrative embodiment of theaccelerator sled 1000 is shown. As discussed above, theaccelerator circuits 1020,communication circuit 830, andoptical data connector 834 are mounted to thetop side 650 of the chassis-lesscircuit board substrate 602. Again, theindividual accelerator circuits 1020 andcommunication circuit 830 are mounted to thetop side 650 of the chassis-lesscircuit board substrate 602 such that no two heat-producing, electrical components shadow each other as discussed above. Thememory devices 720 of theaccelerator sled 1000 are mounted to thebottom side 750 of the of the chassis-lesscircuit board substrate 602 as discussed above in regard to the sled 600. Although mounted to thebottom side 750, thememory devices 720 are communicatively coupled to theaccelerator circuits 1020 located on thetop side 650 via the I/O subsystem 622 (e.g., through vias). Further, each of theaccelerator circuits 1020 may include a heatsink 1070 that is larger than a traditional heatsink used in a server. As discussed above with reference to the heatsinks 870, the heatsinks 1070 may be larger than tradition heatsinks because of the “free” area provided by thememory devices 750 being located on thebottom side 750 of the chassis-lesscircuit board substrate 602 rather than on thetop side 650. - Referring now to
FIG. 12 , in some embodiments, thesled 400 may be embodied as astorage sled 1200. Thestorage sled 1200 is optimized, or otherwise configured, to store data in adata storage 1250 local to thestorage sled 1200. For example, during operation, acompute sled 800 or anaccelerator sled 1000 may store and retrieve data from thedata storage 1250 of thestorage sled 1200. Thestorage sled 1200 includes various components similar to components of thesled 400 and/or thecompute sled 800, which have been identified inFIG. 12 using the same reference numbers. The description of such components provided above in regard toFIGS. 6, 7 , and 8 apply to the corresponding components of thestorage sled 1200 and is not repeated herein for clarity of the description of thestorage sled 1200. - In the
illustrative storage sled 1200, thephysical resources 620 are embodied asstorage controllers 1220. Although only twostorage controllers 1220 are shown inFIG. 12 , it should be appreciated that thestorage sled 1200 may includeadditional storage controllers 1220 in other embodiments. Thestorage controllers 1220 may be embodied as any type of processor, controller, or control circuit capable of controlling the storage and retrieval of data into thedata storage 1250 based on requests received via thecommunication circuit 830. In the illustrative embodiment, thestorage controllers 1220 are embodied as relatively low-power processors or controllers. For example, in some embodiments, thestorage controllers 1220 may be configured to operate at a power rating of about 75 watts. - In some embodiments, the
storage sled 1200 may also include a controller-to-controller interconnect 1242. Similar to the resource-to-resource interconnect 624 of thesled 400 discussed above, the controller-to-controller interconnect 1242 may be embodied as any type of communication interconnect capable of facilitating controller-to-controller communications. In the illustrative embodiment, the controller-to-controller interconnect 1242 is embodied as a high-speed point-to-point interconnect (e.g., faster than the I/O subsystem 622). For example, the controller-to-controller interconnect 1242 may be embodied as a QuickPath Interconnect (QPI), an UltraPath Interconnect (UPI), or other high-speed point-to-point interconnect dedicated to processor-to-processor communications. - Referring now to
FIG. 13 , an illustrative embodiment of thestorage sled 1200 is shown. In the illustrative embodiment, thedata storage 1250 is embodied as, or otherwise includes, astorage cage 1252 configured to house one or more solid state drives (SSDs) 1254. To do so, thestorage cage 1252 includes a number of mountingslots 1256, each of which is configured to receive a correspondingsolid state drive 1254. Each of the mountingslots 1256 includes a number of drive guides 1258 that cooperate to define anaccess opening 1260 of thecorresponding mounting slot 1256. Thestorage cage 1252 is secured to the chassis-lesscircuit board substrate 602 such that the access openings face away from (i.e., toward the front of) the chassis-lesscircuit board substrate 602. As such, solid state drives 1254 are accessible while thestorage sled 1200 is mounted in a corresponding rack 204. For example, asolid state drive 1254 may be swapped out of a rack 240 (e.g., via a robot) while thestorage sled 1200 remains mounted in thecorresponding rack 240. - The
storage cage 1252 illustratively includes sixteen mountingslots 1256 and is capable of mounting and storing sixteen solid state drives 1254. Of course, thestorage cage 1252 may be configured to store additional or fewer solid state drives 1254 in other embodiments. Additionally, in the illustrative embodiment, the solid state drivers are mounted vertically in thestorage cage 1252, but may be mounted in thestorage cage 1252 in a different orientation in other embodiments. Eachsolid state drive 1254 may be embodied as any type of data storage device capable of storing long term data. To do so, the solid state drives 1254 may include volatile and non-volatile memory devices discussed above. - As shown in
FIG. 13 , thestorage controllers 1220, thecommunication circuit 830, and theoptical data connector 834 are illustratively mounted to thetop side 650 of the chassis-lesscircuit board substrate 602. Again, as discussed above, any suitable attachment or mounting technology may be used to mount the electrical components of thestorage sled 1200 to the chassis-lesscircuit board substrate 602 including, for example, sockets (e.g., a processor socket), holders, brackets, soldered connections, and/or other mounting or securing techniques. - As discussed above, the
individual storage controllers 1220 and thecommunication circuit 830 are mounted to thetop side 650 of the chassis-lesscircuit board substrate 602 such that no two heat-producing, electrical components shadow each other. For example, thestorage controllers 1220 and thecommunication circuit 830 are mounted in corresponding locations on thetop side 650 of the chassis-lesscircuit board substrate 602 such that no two of those electrical components are linearly in-line with other along the direction of theairflow path 608. - The
memory devices 720 of thestorage sled 1200 are mounted to thebottom side 750 of the of the chassis-lesscircuit board substrate 602 as discussed above in regard to thesled 400. Although mounted to thebottom side 750, thememory devices 720 are communicatively coupled to thestorage controllers 1220 located on thetop side 650 via the I/O subsystem 622. Again, because the chassis-lesscircuit board substrate 602 is embodied as a double-sided circuit board, thememory devices 720 and thestorage controllers 1220 may be communicatively coupled by one or more vias, connectors, or other mechanisms extending through the chassis-lesscircuit board substrate 602. Each of thestorage controllers 1220 includes a heatsink 1270 secured thereto. As discussed above, due to the improved thermal cooling characteristics of the chassis-lesscircuit board substrate 602 of thestorage sled 1200, none of the heatsinks 1270 include cooling fans attached thereto. That is, each of the heatsinks 1270 is embodied as a fan-less heatsink. - Referring now to
FIG. 14 , in some embodiments, thesled 400 may be embodied as amemory sled 1400. Thestorage sled 1400 is optimized, or otherwise configured, to provide other sleds 400 (e.g., compute sleds 800, accelerator sleds 1000, etc.) with access to a pool of memory (e.g., in two ormore sets memory sled 1200. For example, during operation, acompute sled 800 or anaccelerator sled 1000 may remotely write to and/or read from one or more of the memory sets 1430, 1432 of thememory sled 1200 using a logical address space that maps to physical addresses in the memory sets 1430, 1432. Thememory sled 1400 includes various components similar to components of thesled 400 and/or thecompute sled 800, which have been identified inFIG. 14 using the same reference numbers. The description of such components provided above in regard toFIGS. 6, 7, and 8 apply to the corresponding components of thememory sled 1400 and is not repeated herein for clarity of the description of thememory sled 1400. - In the
illustrative memory sled 1400, thephysical resources 620 are embodied asmemory controllers 1420. Although only twomemory controllers 1420 are shown inFIG. 14 , it should be appreciated that thememory sled 1400 may includeadditional memory controllers 1420 in other embodiments. Thememory controllers 1420 may be embodied as any type of processor, controller, or control circuit capable of controlling the writing and reading of data into the memory sets 1430, 1432 based on requests received via thecommunication circuit 830. In the illustrative embodiment, eachstorage controller 1220 is connected to acorresponding memory set memory devices 720 within the correspondingmemory set sled 400 that has sent a request to thememory sled 1400 to perform a memory access operation (e.g., read or write). - In some embodiments, the
memory sled 1400 may also include a controller-to-controller interconnect 1442. Similar to the resource-to-resource interconnect 624 of thesled 400 discussed above, the controller-to-controller interconnect 1442 may be embodied as any type of communication interconnect capable of facilitating controller-to-controller communications. In the illustrative embodiment, the controller-to-controller interconnect 1442 is embodied as a high-speed point-to-point interconnect (e.g., faster than the I/O subsystem 622). For example, the controller-to-controller interconnect 1442 may be embodied as a QuickPath Interconnect (QPI), an UltraPath Interconnect (UPI), or other high-speed point-to-point interconnect dedicated to processor-to-processor communications. As such, in some embodiments, amemory controller 1420 may access, through the controller-to-controller interconnect 1442, memory that is within the memory set 1432 associated with anothermemory controller 1420. In some embodiments, a scalable memory controller is made of multiple smaller memory controllers, referred to herein as “chiplets”, on a memory sled (e.g., the memory sled 1400). The chiplets may be interconnected (e.g., using EMIB (Embedded Multi-Die Interconnect Bridge)). The combined chiplet memory controller may scale up to a relatively large number of memory controllers and I/O ports, (e.g., up to 16 memory channels). In some embodiments, thememory controllers 1420 may implement a memory interleave (e.g., one memory address is mapped to thememory set 1430, the next memory address is mapped to thememory set 1432, and the third address is mapped to thememory set 1430, etc.). The interleaving may be managed within thememory controllers 1420, or from CPU sockets (e.g., of the compute sled 800) across network links to the memory sets 1430, 1432, and may improve the latency associated with performing memory access operations as compared to accessing contiguous memory addresses from the same memory device. - Further, in some embodiments, the
memory sled 1400 may be connected to one or more other sleds 400 (e.g., in thesame rack 240 or an adjacent rack 240) through a waveguide, using thewaveguide connector 1480. In the illustrative embodiment, the waveguides are 64 millimeter waveguides that provide 16 Rx (i.e., receive) lanes and 16 Rt (i.e., transmit) lanes. Each lane, in the illustrative embodiment, is either 16 Ghz or 32 Ghz. In other embodiments, the frequencies may be different. Using a waveguide may provide high throughput access to the memory pool (e.g., the memory sets 1430, 1432) to another sled (e.g., asled 400 in thesame rack 240 or anadjacent rack 240 as the memory sled 1400) without adding to the load on theoptical data connector 834. - Referring now to
FIG. 15 , a system for executing one or more workloads (e.g., applications) may be implemented in accordance with thedata center 100. In the illustrative embodiment, thesystem 1510 includes anorchestrator server 1520, which may be embodied as a managed node comprising a compute device (e.g., a compute sled 800) executing management software (e.g., a cloud operating environment, such as OpenStack) that is communicatively coupled tomultiple sleds 400 including a large number of compute sleds 1530 (e.g., each similar to the compute sled 800), memory sleds 1540 (e.g., each similar to the memory sled 1400), accelerator sleds 1550 (e.g., each similar to the memory sled 1000), and storage sleds 1560 (e.g., each similar to the storage sled 1200). One or more of thesleds orchestrator server 1520, to collectively perform a workload (e.g., anapplication 1532 executed in a virtual machine or in a container). The managed node 1570 may be embodied as an assembly ofphysical resources 620, such asprocessors 820,memory resources 720,accelerator circuits 1020, ordata storage 1250, from the same ordifferent sleds 400. Further, the managed node may be established, defined, or “spun up” by theorchestrator server 1520 at the time a workload is to be assigned to the managed node or at any other time, and may exist regardless of whether any workloads are presently assigned to the managed node. In the illustrative embodiment, theorchestrator server 1520 may selectively allocate and/or deallocatephysical resources 620 from thesleds 400 and/or add or remove one ormore sleds 400 from the managed node 1570 as a function of quality of service (QoS) targets (e.g., performance targets associated with a throughput, latency, instructions per second, etc.) associated with a service level agreement for the workload (e.g., the application 1532). In doing so, theorchestrator server 1520 may receive telemetry data indicative of performance conditions (e.g., throughput, latency, instructions per second, etc.) in eachsled 400 of the managed node 1570 and compare the telemetry data to the quality of service targets to determine whether the quality of service targets are being satisfied. If the so, theorchestrator server 1520 may additionally determine whether one or more physical resources may be deallocated from the managed node 1570 while still satisfying the QoS targets, thereby freeing up those physical resources for use in another managed node (e.g., to execute a different workload). Alternatively, if the QoS targets are not presently satisfied, theorchestrator server 1520 may determine to dynamically allocate additional physical resources to assist in the execution of the workload (e.g., the application 1532) while the workload is executing - Additionally, in some embodiments, the
orchestrator server 1520 may identify trends in the resource utilization of the workload (e.g., the application 1532), such as by identifying phases of execution (e.g., time periods in which different operations, each having different resource utilizations characteristics, are performed) of the workload (e.g., the application 1532) and pre-emptively identifying available resources in thedata center 100 and allocating them to the managed node 1570 (e.g., within a predefined time period of the associated phase beginning). In some embodiments, theorchestrator server 1520 may model performance based on various latencies and a distribution scheme to place workloads among compute sleds and other resources (e.g., accelerator sleds, memory sleds, storage sleds) in thedata center 100. For example, theorchestrator server 1520 may utilize a model that accounts for the performance of resources on the sleds 400 (e.g., FPGA performance, memory access latency, etc.) and the performance (e.g., congestion, latency, bandwidth) of the path through the network to the resource (e.g., FPGA). As such, theorchestrator server 1520 may determine which resource(s) should be used with which workloads based on the total latency associated with each potential resource available in the data center 100 (e.g., the latency associated with the performance of the resource itself in addition to the latency associated with the path through the network between the compute sled executing the workload and thesled 400 on which the resource is located). - In some embodiments, the
orchestrator server 1520 may generate a map of heat generation in thedata center 100 using telemetry data (e.g., temperatures, fan speeds, etc.) reported from thesleds 400 and allocate resources to managed nodes as a function of the map of heat generation and predicted heat generation associated with different workloads, to maintain a target temperature and heat distribution in thedata center 100. Additionally or alternatively, in some embodiments, theorchestrator server 1520 may organize received telemetry data into a hierarchical model that is indicative of a relationship between the managed nodes (e.g., a spatial relationship such as the physical locations of the resources of the managed nodes within thedata center 100 and/or a functional relationship, such as groupings of the managed nodes by the customers the managed nodes provide services for, the types of functions typically performed by the managed nodes, managed nodes that typically share or exchange workloads among each other, etc.). Based on differences in the physical locations and resources in the managed nodes, a given workload may exhibit different resource utilizations (e.g., cause a different internal temperature, use a different percentage of processor or memory capacity) across the resources of different managed nodes. Theorchestrator server 1520 may determine the differences based on the telemetry data stored in the hierarchical model and factor the differences into a prediction of future resource utilization of a workload if the workload is reassigned from one managed node to another managed node, to accurately balance resource utilization in thedata center 100. - To reduce the computational load on the
orchestrator server 1520 and the data transfer load on the network, in some embodiments, theorchestrator server 1520 may send self-test information to thesleds 400 to enable eachsled 400 to locally (e.g., on the sled 400) determine whether telemetry data generated by thesled 400 satisfies one or more conditions (e.g., an available capacity that satisfies a predefined threshold, a temperature that satisfies a predefined threshold, etc.). Eachsled 400 may then report back a simplified result (e.g., yes or no) to theorchestrator server 1520, which theorchestrator server 1520 may utilize in determining the allocation of resources to managed nodes. - Referring now to
FIG. 16 , asystem 1610, similar to thesystem 1510, for managing a kernel topology for a workload may be implemented in accordance with thedata center 100. In an example embodiment, thesystem 1610 includes anorchestrator server 1620 communicatively coupled with multiple sleds, including acompute sled 1630 andaccelerator sleds compute sled 1630 andaccelerator sleds orchestrator server 1620. The managed node may collectively execute a workload, such as an application (e.g., application 1634). A managed node may be embodied as an assembly of resources (e.g., physical resources), such as compute resources, memory resources, storage resources, or other resources (e.g., accelerator resources), from the same or different sleds or racks. Further, a managed node may be established, defined, or “spun up” by theorchestrator server 1620 at the time a workload is to be assigned to the managed node or at any other time, and may exist regardless of whether any workloads are presently assigned to the managed node. Thesystem 1610 may be located in a data center and provide storage and compute services (e.g., cloud services) to aclient device 1614 that is in communication with thesystem 1610 through anetwork 1612. Theorchestrator server 1620 may support a cloud operating environment, such as OpenStack, and managed nodes established by theorchestrator server 1620 may execute one or more applications or processes (i.e., workloads), such as in virtual machines or containers, on behalf of a user of theclient device 1614. - Illustratively, the
compute sled 1630 includes one or more central processing units (CPUs) 1632 (e.g., a processor or other device or circuitry capable of performing a series of operations) that executes a workload (e.g., application 1634). Theaccelerator sled 1640 includes anaccelerator device 1642. Additionally, thecompute sled 1650 includesaccelerator devices accelerator sled 1660 includesaccelerator devices accelerator devices accelerator device 1642 includeskernel A 1644, kernel B 1645; theaccelerator device 1652 includeskernel A 1653 andkernel B 1654; theaccelerator device 1656 includeskernel A 1657 andkernel B 1658; theaccelerator device 1662 includeskernel A 1663,kernel B 1664,kernel C 1665, andkernel D 1666; and theaccelerator device 1667 includeskernel A 1668,kernel B 1669,kernel C 1670, andkernel D 1671. Each of the accelerated kernels may be embodied as a set of code or a configuration of a portion of the corresponding accelerator device that causes the respective accelerator device to perform one or more accelerated functions (e.g., cryptographic operations, compression operations, etc.). - Each of the accelerator sleds 1640, 1650, and 1660 provide accelerated functions as a service for workloads processed by the managed node. In particular, each
accelerator sled FIG. 16 depicts thecompute sled 1630 executing theapplication 1634. Theapplication 1634 may include functions to be performed in sequence. Thecompute sled 1630 may send a request to the accelerator sleds to accelerate the execution of each function, thereby offloading the execution of the function to an accelerator device residing on the accelerator sled. The accelerator sled may, in response to the request, provision a kernel on the accelerator device. For example, the accelerator sled may load a bit stream (e.g., any data indicative of code executable by an accelerator device to configure itself with a corresponding kernel) associated with the kernel into a slot (e.g., a subset of circuitry or other logic units) of the accelerator device. Theapplication 1634 may include a variety of functions, such as cryptographic operations, machine learning algorithms, and the like. The kernel provisioned on the accelerator device may be suited to accelerate the execution of the function. For example, the underlying function may involve matrix multiplication. The kernel provisioned with the accelerator device may be specific to processing matrix multiplication operations. Once the kernel completes acceleration of the function, the kernel may return resulting data to thecompute sled 1630. Theorchestrator server 1620 may track (e.g., via a database) which kernels are registered to which accelerator sleds and which accelerator devices. - As further described herein, the
orchestrator server 1620 may define a topology for kernel-to-kernel communication as a function of a workload (e.g., the application 1634) across thesystem 1610. More particularly, the topology defines communication links between a given kernel and one or more kernels based on a flow of data in a workload, such as from task to task in a workload. For example, a kernel A (e.g., kernel A 1644) may be mapped, via a topology, to a kernel C (e.g., kernel C 1665).Kernel A 1644 may accelerate a function associated with a task and output the resulting data tokernel C 1665, which in turn accelerates a function associated with another task, using the data output from kernel A. A given kernel may be mapped to another kernel within the same accelerator device, within the same sled, between slots (e.g., subsets of circuitry or other logic units) in the same accelerator device, etc. Further, the mappings may be based on various characteristics, such as processing requirements, size of the data being processed in a task, a location of the accelerator device or sled relative to the compute sled executing a workload, and the like. - Further still, the
orchestrator server 1620 may scale accelerated kernel resources according to the kernel topology. In particular, theorchestrator server 1620 may, as a function of the resource utilization, re-provision a kernel on a number of accelerator devices in thesystem 1610. Continuing the previous example, the kernel C may be provisioned onaccelerator devices accelerator devices orchestrator server 1620, in response, may provision additional instances of kernel C on other accelerator devices, such asaccelerator devices accelerator devices orchestrator server 1620, in response, may de-provision the kernel C in one of theaccelerator devices system 1610 as compared to typical systems. - In addition, the
orchestrator server 1620 may scale accelerated kernel resources in response to detecting that a given accelerator device is in a critical power state. For instance, each accelerator device may report power consumption to theorchestrator server 1620. Theorchestrator server 1620 may determine that power consumption in an accelerator device configured with a given kernel exceeds a specified threshold. In response, theorchestrator server 1620 may identify an accelerator device in the system that is available (e.g., is at a suitable power consumption level) to be provisioned with the kernel. Once identified, theorchestrator server 1620 may provision the kernel on the accelerator device and update the kernel topology. As a result, power consumption by the kernel is partially shifted to the additional accelerator device, reducing power consumption in the accelerator device previously in a critical power state. - In addition, while the
orchestrator server 1620 is configured to provision kernels on accelerator devices in thesystem 1610, an accelerator sled (e.g., accelerator sleds 1640, 1650, or 1660) that is configured with a kernel as part of the topology may store a kernel bit stream associated with another kernel to which the configured kernel is mapped. The underlying workload (e.g., application 1634) may identify that further additional accelerator devices should be configured with the kernel (e.g., as a function of observed telemetry data). As further described herein, the accelerator sled may include logic to provision an accelerator device (e.g., on another accelerator sled) with the other kernel. To do so, the accelerator sled may broadcast a request packet to accelerator devices to determine which of the devices are available (e.g., currently not configured with a kernel, has resources to accommodate execution by the kernel, etc.). In response, one or more of the accelerator devices may return a response to the accelerator sled. The accelerator sled may identify which of the accelerator devices to provision as a function of one or more characteristics of each of the available devices, such as current resources available on the device. Once identified, the kernel may encapsulate the stored bit stream of the other kernel in one or more provisioning packets and send the provisioning packets to the accelerator device. - Referring now to
FIG. 17 , theorchestrator server 1620 may be embodied as any type of compute device capable of performing the functions described herein, including receiving a kernel configuration request to provision kernels on multiple accelerator devices, determining, as a function of one or more requirements of a workload, a topology of kernels to service the request, and configure the kernels with the accelerator devices according to the determined topology. Theorchestrator server 1620 may also be embodied as any type of compute device capable of detecting whether an accelerator device configured with a kernel is in a critical power state, determining another accelerator device that is available to be configured with the kernel, and configuring, in response to a determination that the accelerator device is in a critical power state, the other accelerator device with the kernel, where the kernel configured with the accelerator device is to share acceleration of execution of a workload with the kernel configured with the other accelerator device. - As shown in

Thecommunication circuitry 1710 may be configured to use any one or more communication technology (e.g., wired or wireless communications) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, etc.) to effect such communication. - The
illustrative communication circuitry 1710 includes a network interface controller (NIC) 1712, which may also be referred to as a host fabric interface (HFI). TheNIC 1712 may be embodied as one or more add-in-boards, daughter cards, network interface cards, controller chips, chipsets, or other devices that may be used by theorchestrator server 1620 to connect with another compute device (e.g., thecompute sled 1630, the accelerator sleds 1640, 1650, and 1660, etc.).

FIG. 18 , anaccelerator sled 1800 may be embodied as any type of compute device capable of performing the functions described herein, including receiving a request by a workload to provision a kernel on an accelerator device, identifying an accelerator device on which to provision the kernel, and configuring the identified accelerator device with the kernel. Theaccelerator sled 1800 may be representative of any of the accelerator sleds 1640, 1650, or 1660 depicted inFIG. 16 . As shown inFIG. 18 , theaccelerator sled 1800 includes acompute engine 1802, an I/O subsystem 1808,communication circuitry 1810, one or moredata storage devices 1814, and one ormore accelerator devices 1818.

Further, eachaccelerator device 1810 may send data via theNIC 1812 to other accelerator devices in thesystem 1610, based on a kernel topology defined by theorchestrator server 1620. Eachaccelerator device 1818 may be embodied as any device or circuitry (e.g., a specialized processor, an FPGA, an ASIC, a GPU, reconfigurable hardware, etc.) capable of accelerating the execution of a function. - The
client device 1614 and thecompute sled 1630 may have components similar to those described inFIG. 18 . The description of those components of theorchestrator server 1620 and theaccelerator sled 1800 is equally applicable to the description of components of those devices and is not repeated herein for clarity of the description.

client device 1614, theorchestrator server 1620, and thesleds network 1612, which may be embodied as any type of wired or wireless communication network, including global networks (e.g., the Internet), local area networks (LANs) or wide area networks (WANs), cellular networks (e.g., Global System for Mobile Communications (GSM), 3G, Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), etc.), digital subscriber line (DSL) networks, cable networks (e.g., coaxial networks, fiber networks, etc.), or any combination thereof. - Referring now to
FIG. 19 , theorchestrator server 1620 may establish anenvironment 1900 during operation. Illustratively, theenvironment 1900 includes anetwork communicator 1920 and atopology manager 1930. Each of the components of theenvironment 1900 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of theenvironment 1900 may be embodied as circuitry or a collection of electrical devices (e.g.,network communicator circuitry 1920,topology manager circuitry 1930, etc.). It should be appreciated that, in such embodiments, one or more of thenetwork communicator circuitry 1920 or thetopology manager circuitry 1930 may form a portion of one or more of thecompute engine 1702, thecommunication circuitry 1710, the I/O subsystem 1708, and/or other components of theorchestrator server 1620. - In the illustrative embodiment, the
environment 1900 includeskernel topology data 1902, which may be embodied as any data indicative of kernel-to-kernel mappings for a workload. Thekernel topology 1902 may indicate a flow of data originating from the underlying application to one or more kernels in sequence and flowing back to the application. For example, a kernel A may accelerate a function using data provided by the application and send the result of the acceleration to a kernel B. In turn, the kernel B accelerates a function using the resulting data sent by kernel A as input, and so on. Thekernel topology data 1902 is also indicative of kernel configurations on accelerator devices in thesystem 1610. For example,kernel topology data 1902 may include data specifying that kernel A is configured onaccelerator devices - The
environment 1900 also includespolicy data 1904, which may be embodied as any data indicative of conditions, which, when triggered, cause theorchestrator server 1620 to scale kernel instances in one or more of the accelerator devices of thesystem 1610. Theorchestrator server 1620 may, in response to a condition trigger, provision additional instances of a kernel inside the same accelerator device on which the kernel is presently configured, such as in another slot of the accelerator device. In addition, theorchestrator server 1620 may provision additional instances of a kernel inside the same accelerator sled on which the kernel is presently configured, such as in another accelerator device residing on the accelerator sled. In addition, theorchestrator server 1620 may provision additional instances of a kernel on an accelerator device of another accelerator sled in thesystem 1610. Further, theorchestrator server 1620 may remove kernel instances from an accelerator device after a condition is triggered (e.g., scenarios in which resource utilization falls below a specified threshold). Policies may specify that the accelerator device on which the kernel is provisioned be determined as a function of characteristics of the accelerator device, such as the availability of the accelerator device (e.g., whether the accelerator device has resources to be configured with the kernel and utilization to process workload data), the location of the accelerator device relative to the compute sled executing the workload, the location of the accelerator device relative to other kernels linked to the kernel according to thekernel topology data 1902, and the like. - The
environment 1900 also includestelemetry data 1906, which may be embodied as any data indicative of observed performance of accelerator sleds and accelerator devices in thesystem 1610. Telemetry may include metrics such as power consumption of a given sled or device, amount of kernel connections, latency, average period of connections, amount of data transferred per connection, etc. Theorchestrator server 1620 may receivetelemetry data 1906 from each accelerator sled. Alternatively or in addition, an external resource monitor may observe usage in the accelerator sleds and report the correspondingtelemetry data 1906 to theorchestrator server 1620. - Illustratively, the
network communicator 1920, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to facilitate inbound and outbound network communications (e.g., network traffic, network packets, network flows, etc.) to and from theorchestrator server 1620, respectively. To do so, thenetwork communicator 1920 is configured to receive and process data packets from one system or computing device (e.g., the compute sled 1630) and to prepare and send data packets to another computing device or system (e.g., the accelerator sleds 1640, 1650, and 1660). Accordingly, in some embodiments, at least a portion of the functionality of thenetwork communicator 1920 may be performed by thecommunication circuitry 1710, and, in the illustrative embodiment, by theNIC 1712. - The
topology manager 1930, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof, is configured to identify available accelerator device resources, determinekernel topology data 1902 as a function of a workload and the available accelerator device resources, and provision accelerated kernels on the accelerator devices according to thekernel topology data 1902. Thetopology manager 1930 also scales kernel instances on the accelerator devices as a function of observedtelemetry data 1906. As shown, thetopology manager 1930 includes aresource discovery component 1932, aprovision component 1934, and amonitor component 1936. - In one embodiment, the
resource discovery component 1932 is configured to identify resource availability in accelerator devices of thesystem 1610, such as inaccelerator devices resource discovery component 1932 may query each accelerator device for a present resource utilization or other characteristics, such a total amount of slots on the device, an amount of slots configured with kernels on the device, a device location, and the like. Theresource discovery component 1932 may do similar for the accelerator sleds on which the accelerator devices reside. For example, theresource discovery component 1932 may query an accelerator sled for available accelerator devices therein. Theresource discovery component 1932 also determines kernel bit streams applicable to a given workload. For example, a given workload may be configured to execute using proprietary kernels designed for the workload or other third-party kernels that are targeted to performing functions associated with one or more workload tasks. A compute sled executing a workload may send data describing the workload to theorchestrator server 1620, and in turn, theresource discovery component 1932 may determine suitable kernels for the workload. Further, theresource discovery component 1932 may determine a storage location of each kernel bit stream used for the workload. - In the illustrative embodiment, the
provision component 1934 is configured to generate a kernel topology as a function of the available resources in thesystem 1610 and workload characteristics (e.g., resource requirements of the workload, functions included with each workload task, and the like). For example, to do so, theprovision component 1934 may evaluate the location of compute sled executing a given workload and determine available accelerator devices that are located relatively near (e.g., within a predefined distance) to the compute sled for satisfying a latency target. Theprovision component 1934 may also evaluate an amount of processing power required for a given workload task and identify which of the available resources is capable of providing such processing power. Theprovision component 1934 can determine, based on such evaluation, a configuration and routing of kernels on the accelerator sleds. Theprovision component 1934 is further configured to load kernel bit stream data in one or more accelerator devices according to the kernel topology. For example, theprovision component 1934 may obtain the kernel bit stream data from a previously identified storage location and send the bit stream data to a given accelerator device. More specifically, theprovision component 1934 may send the bit stream to the accelerator sled on which the accelerator device resides, and in turn, the accelerator sled may program the bit stream in a designated slot of the accelerator device. Theprovision component 1934 may write and maintain a record indicative of the location of the kernel in thekernel topology data 1902. The record may also indicate one or more kernels to which to send data and one or more kernels from which to receive data. The record may also indicate other accelerator devices that are configured with the kernel. - In one embodiment, the
monitor component 1936 is configured to collect telemetry data from accelerator sleds (e.g., accelerator sleds 1640, 1650, and 1660) and the devices residing thereon. Themonitor component 1936 may do so in a variety of manners. For example, themonitor component 1936 may regularly query a given accelerator sled for telemetry data. As another example, the accelerator subsystem interface described above may provide metrics in each accelerator device at specified intervals. As another example, an external monitor may collect telemetry data from each accelerator sled and send the collected telemetry data to themonitor component 1936. Themonitor component 1936 may store the telemetry data on theorchestrator server 1620 in a data store local to the server (e.g., as telemetry data 1906). - In one embodiment, the
provision component 1934 is further configured to scale kernel instances in accelerator devices for a given workload as a function of thetelemetry data 1906 and thepolicy data 1904. For example, thetelemetry data 1906 may indicate that an amount of connections between one kernel and another kernel is relatively high. Further, thepolicy data 1904 may indicate that if an amount of connections exceeds a specified threshold, the amount of instances for one or both of the kernels should be increased. In response, theprovision component 1934 may identify one or more accelerator devices that satisfy requirements ofpolicy data 1904 for provisioning additional kernel instances. Once identified, theprovision component 1934 may configure the kernel instances on the accelerator device (e.g., by sending kernel bit stream data to the accelerator device and causing the accelerator device to load the kernel bit stream). Theprovision component 1934 may be configured to update thekernel topology data 1902 to include the added kernel instance to the accelerator device. Further, in the illustrative embodiment, theprovision component 1934 may scale kernel instances on additional accelerator devices to shift power consumption across the additional accelerator devices. For instance, thepolicy data 1904 may include a scaling condition that is triggered when power consumption in a given accelerator device (or sled) exceeds a specified threshold or otherwise reaches a critical power state. - It should be appreciated that each of the
resource discovery component 1932,provision component 1934, and monitorcomponent 1936 may be separately embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof. For example, thediscovery component 1932 may be embodied as a hardware component, while the provision component and themonitor component 1936 are embodied as virtualized hardware components or as some other combination of hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof. - Referring now to
FIG. 20 , theaccelerator sled 1800 may establish anenvironment 2000 during operation. Of course, any of the accelerator sleds 1640, 1650, 1660 may similarly establish theenvironment 2000 during operation. Illustratively, theenvironment 2000 includes anetwork communicator 2020 and anaccelerator device manager 2030. Each of the components of theenvironment 2000 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of theenvironment 2000 may be embodied as circuitry or a collection of electrical devices (e.g.,network communicator circuitry 2020, acceleratordevice manager circuitry 2030, etc.). It should be appreciated that, in such embodiments, one or more of thenetwork communicator circuitry 2020 or acceleratordevice manager circuitry 2030 may form a portion of one or more of thecompute engine 1802, thecommunication circuitry 1810, the I/O subsystem 1808, and/or other components of theaccelerator sled 1800. As shown, theenvironment 2000 includeskernel topology data 2002, which may be embodied as any data indicative of mappings of kernel configurations in thesystem 1610, similar to that of thekernel topology data 1902 described above. Further, theenvironment 2000 includestelemetry data 2004, which may be embodied as any data indicative of observed performance of theaccelerator sled 1800 and accelerator devices 1818 (e.g., power consumption, amount of kernel connections, latency, average period of connections, amount of data transferred per connection, etc.). Further still, theenvironment 2000 includes kernelbit stream data 2006, which may be embodied as any data indicative of a predefined bit stream representative of a kernel for accelerating one or more functions of a workload (e.g., machine learning algorithms, cryptographic operations, compression functions, and so on). The kernelbit stream data 2006 includes bit streams of kernels not configured within anaccelerator device 1818 but may be representative of a kernel that sends or receives data to a kernel configured with the accelerator device 1818 (also referred to herein as a “target kernel”). - The
network communicator 2020, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to facilitate inbound and outbound network communications (e.g., network traffic, network packets, network flows, etc.) to and from theaccelerator sled 1800, respectively. To do so, thenetwork communicator 2020 is configured to receive and process data packets from one system or computing device (e.g., the orchestrator server 1620) and to prepare and send data packets to another computing device or system (e.g., thecompute sled 1630, orother accelerator devices network communicator 2020 may be performed by thecommunication circuitry 1810, and, in the illustrative embodiment, by theNIC 1812. - The
accelerator device manager 2030, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof, is configured to receive a request by a workload to provision a kernel on one of theaccelerator devices 1818, identify one of theaccelerator devices 1818 on which to provision the kernel, and configure the identified accelerator device with the kernel. As shown, theaccelerator device manager 2030 includes autilization manager 2034 and akernel manager 2036. - In one embodiment, the
utilization manager 2034 is configured to evaluate kernel-to-kernel activity between a kernel configured with theaccelerator devices 1818 and target kernels connected with the kernel via thekernel topology data 2002. For instance, theutilization manager 2034 may observetelemetry data 2004 relating to theaccelerator devices 1818 with which the kernel is configured and determine, as a function of observed telemetry between the kernels (e.g., communication latency, an amount of connections established between the kernels within a given time period, etc.), whether to provision additional instances of target kernels on another accelerator device in thesystem 1610. For example, theutilization manager 2034 may determine to provision additional instances in the event that latency between kernels exceeds a specified threshold. - In one embodiment, the
kernel manager 2036 is configured to provision kernelbit stream data 2006 indicative of a target kernel on one or more accelerator devices in thesystem 1610. To do so, thekernel manager 2036 may broadcast a request packet to accelerator devices in thesystem 1610. The packet may include data indicative of a request for a response from accelerator devices that are not presently configured with any kernel (or are otherwise not presently in use). Thekernel manager 2036 may then receive a response to the packet from such accelerator devices. The response may include characteristics of the accelerator device, such as a device location, total number of slots on the accelerator device, total number of available slots (e.g., those not presently being used to perform an accelerated function), and the like. Thekernel manager 2036 may, based on the characteristics, determine which of the accelerator devices to provision with the target kernel. - Once determined, the
kernel manager 2036 may retrieve a bit stream associated with the target kernel and encapsulate the bit stream in one or more provisioning packets. Thekernel manager 2036 may then send the provisioning packets to the accelerator sled in which the accelerator device resides. The provisioning packets may include additional data that directs a destination accelerator sled to load the bit stream into one of the slots of the accelerator device. In response, the receiving accelerator sled loads the kernel. Thekernel manager 2036 may update thekernel topology data 2002 to indicate that the target kernel is loaded on the additional accelerator device. Further, thekernel manager 2036 notifies theorchestrator server 1620 that the additional accelerator device has been provisioned. In turn, theorchestrator server 1620 may update thekernel topology data 1902 as a function of the notification. - Referring now to
FIG. 21 , theorchestrator server 1620, in operation, may execute amethod 2100 to determine a topology of accelerated kernels in thesystem 1610. As shown, themethod 2100 begins with block 2102, where theorchestrator server 1620 receives a kernel configuration request from a compute sled (e.g., the compute sled 1630) executing a workload. For example, theorchestrator server 1620 may receive the request at initialization of the workload. The request may include several resource requirements of the workload, a description of each task in the workload, and functions included in each task. - In block 2104, the
orchestrator server 1620 determines one or more kernel topologies as a function of the workload requirements provided with the request. In particular, inblock 2106, theorchestrator server 1620 determines characteristics of each accelerator device in thesystem 1610. Example characteristics include a power state, total amount of slots available, present amount of kernels loaded in each slot, a location of the device, and the like. Inblock 2108, theorchestrator server 1620 determines one or more configurations of accelerator devices with the kernels as a function of characteristics that satisfy the workload requirements. For example, the workload requirements may require that any function to be accelerated should be performed by an accelerator device in a sled that is located relatively near (e.g., within a predefined distance of) the compute sled executing the workload. Theorchestrator server 1620 may determine, based on such a requirement, to load kernels on accelerator devices that satisfy those requirements. - In
block 2110, theorchestrator server 1620 may optionally return the determined kernel topologies to the requesting compute sled for selection. In turn, the compute sled may determine a kernel topology to select based on the workload requirements and any additional criteria. In addition, a user may also make a selection of one of the determined kernel topologies. Inblock 2112, theorchestrator server 1620 receives the selection. Inblock 2114, theorchestrator server 1620 configures the accelerator devices according to the determined kernel topology. In particular, inblock 2116, theorchestrator server 1620 identifies, based on characteristics of each accelerator device as provided in the kernel topology, one or more accelerator devices to provision. Theorchestrator server 1620 may identify the network address of each accelerator device to provision. - In block 2118, the
orchestrator server 1620 performs the following for each identified accelerator device. Inblock 2120, theorchestrator server 1620 retrieves the kernel bit streams to provision on the accelerator device according to the kernel topology. For example, theorchestrator server 1620 may retrieve the bit streams from a data store of kernel bit streams associated with the workload. Inblock 2122, theorchestrator server 1620 loads the bit streams on the accelerator device. More particularly, theorchestrator server 1620 may transmit the kernel bit stream to the accelerator sled. The accelerator sled may include logic to configure the kernel bit stream on a target accelerator device when received from theorchestrator server 1620. In other embodiments, theorchestrator server 1620 may encapsulate the kernel bit stream in provisioning packets and transmit the packets to the accelerator sled. The provisioning packets may include additional data that direct the accelerator sled to configure the target accelerator device with the kernel. - In
block 2124, theorchestrator server 1620 maps the loaded kernels according to the topology. In particular, theorchestrator server 1620 may propagate the kernel topology data to accelerator sleds in thesystem 1610. The accelerator sled may configure network connections between kernels based on the information provided by the kernel topology data. For example, if a kernel A executing in an accelerator device A is to communicate with a kernel B executing in an accelerator device B, the accelerator sled of kernel A may configure accelerator device A with routing information (e.g., the network address of accelerator device B) to allow kernel A to communicate with kernel B. - Referring now to
FIG. 22 , theorchestrator server 1620, in operation, may execute amethod 2200 to scale a configuration of accelerated kernels in the system as a function of a kernel topology. As shown, themethod 2200 begins in block 2202, in which theorchestrator server 1620 monitors kernel resource utilization. In particular, in block 2204, theorchestrator server 1620 collects telemetry data associated with the accelerator sleds (e.g., accelerator sleds 1640, 1650, or 1660). For example, each accelerator sled may transmit telemetry data to theorchestrator server 1620. As another example, theorchestrator server 1620 may obtain telemetry data in network devices or components (e.g., switches, NICs, etc.) in thesystem 1610 connecting kernels with one another. - In
block 2206, theorchestrator server 1620 evaluates the monitored kernel resource utilization relative to scaling policies. More particularly, theorchestrator server 1620 determines, as a function of the scaling policies, whether the kernels presently provisioned with the accelerator devices should be scaled up or down based on the present resource utilization. As stated, the scaling policies provide one or more conditions, which if triggered, cause theorchestrator server 1620 to re-provision one or more kernels. Inblock 2208, theorchestrator server 1620 determines whether a scaling condition is triggered. If not, themethod 2200 loops back to block 2202, in which theorchestrator server 1620 continues to monitor kernel resource utilization. Otherwise, inblock 2210, theorchestrator server 1620 determines whether the triggered condition relates to power management, such as power consumption or a present power state of a given accelerator sled or device. If so, theorchestrator server 1620 may initiate kernel scaling to shift power consumption to multiple accelerator sleds, further described relative toFIGS. 23, 24A, and 24B . - If the condition is not related to power management, then in block 2212, the
orchestrator server 1620 identifies one or more kernels to re-provision as a function of the triggered scaling condition. For example, a policy may specify that if latency is high in kernel A when communicating with kernel C at all accelerator devices configured with kernel C, then instances of kernel C should be scaled up. Inblock 2214, theorchestrator server 1620 re-provisions kernels according to the triggered scaling condition. Inblock 2216, theorchestrator server 1620 loads or removes the kernel instance in or from accelerator sleds based on the triggered condition. Continuing the previous example, the triggered scaling condition indicates that additional kernel C instances should be provisioned. The scaling condition may also indicate other rules for provisioning the instances, such as relative proximity to an accelerator device configured with kernel A. Theorchestrator server 1620 may identify available accelerator devices on which to configure the kernel. Once identified, theorchestrator server 1620 may send a bit stream corresponding to the kernel to the accelerator devices. In block 2218, theorchestrator server 1620 updates the kernel topology data to include the additional instances and the device locations of the instances. - Referring now to
FIG. 23 , theorchestrator server 1620, in operation, may execute amethod 2300 to provision additional instances of a kernel executing on an accelerator device as a function of a power state associated with the accelerator device. As shown, themethod 2300 begins inblock 2302, in which theorchestrator server 1620 detects, as a function of monitored telemetry data, that an accelerator device configured with a kernel accelerating functions for a workload is in a critical power state. The telemetry data collected from an accelerator device may include power consumption as a metric for evaluation by theorchestrator server 1620. If the power consumption exceeds a threshold specified by a scaling policy, theorchestrator server 1620 may determine that the accelerator device (or sled) is currently in a critical power state. - In
block 2304, theorchestrator server 1620 identifies a kernel that is configured with the accelerator device that is in a critical power state. For example, to do so, theorchestrator server 1620 may evaluate kernel topology data to determine a configuration of the accelerator device. The configuration may specify one or more kernels presently provisioned to the accelerator device. Inblock 2306, theorchestrator server 1620 determines available accelerator devices in thesystem 1610 that can be provisioned with the kernel. For instance, theorchestrator server 1620 may evaluate accelerator devices that do not have a kernel presently configured therewith. Further, theorchestrator server 1620 may evaluate characteristics of the accelerator devices, such as device location and a present load on the accelerator device. Theorchestrator server 1620, as a function of the characteristics, may select one or more of the accelerator devices on which to provision the kernel. - In
block 2308, theorchestrator server 1620 provisions the identified kernel on the selected accelerator devices. In particular, inblock 2310, theorchestrator server 1620 loads the kernel on the accelerator devices. To do so, theorchestrator server 1620 may retrieve a bit stream corresponding to the kernel from a predetermined data store and send the bit stream to the accelerator devices, using similar techniques to those described above. In turn, the receiving accelerator devices may configure the kernel bit stream. Inblock 2312, theorchestrator server 1620 updates the kernel topology data to include the provisioning of the kernel instances on the additional accelerator devices. Further, theorchestrator server 1620 propagates the updated kernel topology data to the accelerator sleds in thesystem 1610. As a result, the workload data processed by the kernel is shared among accelerator devices, thereby shifting power consumption. - Referring now to
FIGS. 24A and 24B , diagrams of an example embodiment of provisioning additional instances of a kernel to reduce power consumption in an accelerator sled is shown.FIG. 24A depicts akernel A 2405 and akernel B 2410 communicating via anetwork 2415. Thenetwork 2415 is representative of one or more networking devices (e.g., a switch device, NIC, etc.) interconnecting thekernel A 2405 andkernel B 2410 according to a kernel topology. Thekernel A 2405 accelerates a function of a workload and transmits resulting data from the function to thekernel B 2410 over thenetwork 2415. Illustratively, the entirety of the data is transmitted to the kernel B 2410 (represented by the indication of 100% bandwidth). Further,FIG. 24A depicts the kernel B 2410 (e.g., the accelerator device associated with the kernel B) in a critical power state. As stated, telemetry data collected from the accelerator device configured with kernel B may provide a power consumption metric that may indicate the critical power state. -
FIG. 24B depicts the result of scaling an additional kernel B instance (kernel B 2412) to offset power consumption to another accelerator device. Thekernel B 2412 may reside an accelerator device of another sled. Illustratively, data transmitted over thenetwork 2415 bykernel A 2405 is shared between thekernel B 2410 andkernel B 2412, represented by the “normal power state” indication in each. - Referring now to
FIG. 25 , the accelerator sled 1800 (or any of the accelerator sleds 1640, 1650, 1660) may, in operation, execute amethod 2500 for provisioning, via an in-band communication by an accelerator device in thesled 1800, a target kernel on another accelerator device. As shown, themethod 2500 begins inblock 2502, where theaccelerator sled 1900 pre-emptively stores, via the workload, a bit stream associated with the target kernel. For example, during provisioning of the accelerator devices according to the kernel topology, theorchestrator server 1620 may transmit the bit stream of the target kernel to theaccelerator sled 1800. Theaccelerator sled 1800 may store the bit stream in a local data store. - In
block 2504, theaccelerator sled 1800 identifies one or more unused accelerator devices on which to provision the kernel. In particular, inblock 2506, the kernel broadcasts a resource request packet via the kernel-to-kernel communication network. The packet is indicative of a request for accelerator devices that presently are not configured with a kernel or are otherwise not in use. The accelerator devices may reside on another sled separate from thesled 1800. Inblock 2506, the kernel receives a response to the request from one or more of the unused accelerator devices. The response may include data indicative of one or more characteristics of the responding accelerator device. Inblock 2510, theaccelerator sled 1800 selects one or more of the accelerator devices as a function of the characteristics of each sled. - In
block 2512, theaccelerator sled 1800 configures the selected accelerator device (or devices) with the target kernel. In particular, inblock 2514, theaccelerator sled 1800 encapsulates the previously stored bit stream data associated with the target kernel in one or more provisioning packets. The provisioning packets may also include data causing the receiving accelerator sled to configure the bit stream data in a slot of the accelerator device. Inblock 2516, theaccelerator sled 1800 sends the provisioning packets to the identified accelerator devices over the kernel-to-kernel network. More particularly, theaccelerator sled 1800 may specify a network address of the accelerator sled hosting the accelerator device in the destination address of each packet. In turn, the target accelerator sled receives the packets and may configure the bit stream data in the accelerator device. - In
block 2518, theaccelerator sled 1800 optionally notifies theorchestrator server 1620 of the in-band provisioning of the target kernel on the accelerator device. For instance, theaccelerator sled 1800 may transmit data indicative of the configuration, the type of the kernel, the target accelerator sled and device, and the like. In turn, theorchestrator server 1620 may update kernel topology data to include the configuration of the kernel on the accelerator device. Theorchestrator server 1620 may also propagate the update to other accelerator sleds in thesystem 1610. - In block 2520, as a result of the in-band provisioning, the kernel configured in the
accelerator sled 1800 may transmit workload data to the target kernel in the newly-provisioned accelerator device. Referring now toFIGS. 26A and 26B , diagrams of an example embodiment of provisioning, via in-band communication by an accelerator device, a kernel on another accelerator device is shown.FIG. 26A depicts akernel A 2605 receiving processing workload data from anapplication 2607. For example, theapplication 2607 may be representative of theapplication 1634. Thekernel A 2605 is configured to output resulting workload data tokernel B 2610 via a kernel-to-kernel communication network 2615. Thenetwork 2615 is representative of one or more networking devices (e.g., a switch device, NIC, etc.) interconnecting thekernel A 2610 and thekernel B 2610 according to a kernel topology. - The kernel A may, via the
application 2607, determine that additional instances ofkernel B 2610 should be provisioned on another accelerator device. For example, theapplication 2607 may determine that a number of connections (or other observed telemetry data) made with the kernel B exceeds some specified threshold. In some cases, it is preferable for thekernel A 2605 to provision an additional instance of kernel B on another accelerator device. For instance, the accelerator sled configured with kernel A may detect an increasing load on resource utilization on kernel B sooner than theorchestrator server 1620 does. Further, in some cases, provisioning anadditional kernel B 2610 instance may have a lower operational cost, such as in network latency, than if theorchestrator server 1620 provisions the kernel (e.g., in cases where kernel A provisions anadditional kernel B 2610 instance on the same sled as kernel A). - Illustratively, the
kernel A 2605 broadcasts a resource request packet via the kernel-to-kernel communication network 2615 (as indicated by arrow 2618). The resource request packet may be received atunused resources 2612, which are representative of accelerator devices in thesystem 1610 that are not presently configured with a kernel instance or devices that include available slots. The accelerator devices may reside on the same accelerator sled askernel A 2605 or on a separate accelerator sled.Unused resources 2612 that are available to be configured with an instance of kernel B may send a response tokernel A 2605, which may include data indicative of characteristics of anunused resource 2612. Thekernel A 2605 may, via theapplication 2607, determine one of theunused resources 2612 to provision with the kernel B instance as a function of the characteristics. -
FIG. 26B depictskernel A 2605 provisioning a new kernel B instance (kernel B 2610′). In particular, thekernel A 2605 sends one or more provisioning packets including a bit stream corresponding to the determined unused resource 2612 (e.g., an accelerator device) over the network 2615 (as indicated by arrow 2620). Once received, the accelerator device may provision the bit stream in one of the slots therein. Further, thekernel A 2605 may send an update to the kernel topology data to theorchestrator server 1620. As a result, thekernel A 2605 may output kernel data to both instances ofkernel B - Illustrative examples of the technologies disclosed herein are provided below.
