Before describing embodiments of the present application in detail, a concept of routing and related technologies is first explained.
Routing: routing refers to the network-wide process of determining an end-to-end path as a packet travels from a source to a destination. Routers implement network interconnections by forwarding packets. A router typically connects two or more logical ports, identified by IP subnets or point-to-point protocols, with at least 1 physical port. The router determines an output port and a next hop address according to a network layer address in the received data packet and a routing table maintained inside the router, and rewrites a link layer data packet header to realize forwarding of the data packet. Routers reflect the current network topology by dynamically maintaining routing tables, which are maintained by other routers on the network exchanging routing and link information.
GPU (graphics processing unit): the graphics processor, also called a display core, a visual processor, and a display chip, is a microprocessor that is dedicated to image and graphics related operations on personal computers, workstations, game machines, and some mobile devices (e.g., tablet computers, smart phones, etc.).
Displaying and storing: the video memory, also called a frame buffer, is used for storing rendering data processed or to be extracted by the video card chip. As with the memory of a computer, video memory is the means used to store graphics information to be processed.
The communication protocol is as follows: a communication protocol refers to the rules and conventions that must be followed by two entities to complete a communication or service.
Interlaken: also known as ILKN, is a protocol for high-speed data transmission between chips.
Serdes: also written as SERDES, is short for SERializer/DESerializer. It is a mainstream Time Division Multiplexing (TDM), point-to-point (P2P) serial communication technology. That is, at the transmitting end, the multi-path low-speed parallel signals are converted into high-speed serial signals, and finally, at the receiving end, the high-speed serial signals are converted into low-speed parallel signals again through a transmission medium (an optical cable or a copper wire). The point-to-point serial communication technology fully utilizes the channel capacity of a transmission medium, reduces the number of required transmission channels and device pins, and improves the transmission speed of signals, thereby greatly reducing the communication cost.
SMC: the control unit in the GPU chip can access the whole address space of the GPU and can access 256T physical memory under the address width of 48 bits.
FW: a program running on the SMC.
InitDone register: a register used in ILKN protocol into which the value written is automatically synchronized into the initdoneshandow register of the docking port. The InitDone register is used to prepare for port handshaking. Typically, there is one InitDone register per port.
Initdoneshedow register: a register used in ILKN protocol whose value follows the value of the InitDone register of the docking port. Typically, there is one initdonoshadow register per port.
TopoInfo register: a register used in ILKN protocol may be written with 64bits of data that will be automatically synchronized by the hardware to the TopoInfoShadow register of the docking port. Typically, there is one TopoInfo register per port.
Topolnfosgadow register: a register used in the ILKN protocol, the value of which varies following the value of the docking port TopoInfo register. Typically, there is one TopoInfoShadow register per port.
Host equipment: also referred to as a host, may be a host computer or the like. When communication is performed between a plurality of terminals, processing needs to be performed by the host.
Topological structure: topology refers to the physical layout of various devices such as computers interconnected by transmission media, and refers to the geometry formed during the interconnection process, which can represent the network configuration and interconnection of network servers and workstations.
Fig. 1 illustrates an exemplary application scenario of a route configuration method according to some embodiments of the present application. As shown in fig. 1, the application scenario may include at least one second-type device and a plurality of first-type devices. The first type of devices may be interconnected and communicate through the ports. And the first type device may communicate with the second type device by means of wired or wireless communication, for example, via a bus. The first type of device may be a GPU card or other computing device. The second type of device may be a device that contains computing functionality, such as a HOST device or the like.
In this embodiment, each of the first type devices comprises a graphics processor, routing means for routing to a plurality of other first type devices and a port for communicating with the other devices. A method implemented at a first type of device for route configuration comprising: acquiring port connection information of a first type device and other first type devices; sending the port connection information to the second type equipment, so that the second type equipment determines the routing information among the first type equipment based on the port connection information; acquiring routing information of communication between the first-class equipment and other first-class equipment from the second-class equipment; and configuring a routing device of the first type device based on the routing information.
It should be noted that fig. 1 only shows an exemplary embodiment of one application scenario. For different application scenarios, the number of the first-type devices, the number of the second-type devices, the number of the ports of the first-type devices, the connection relationship between the first-type devices, and the like may all be changed accordingly, which is not limited herein. And the connection between the second type of device and the first type of device may adopt common connection manners, including but not limited to wired connection, wireless connection, and the like, and may be connected through a bus, for example, which is not limited herein.
It should be noted that the first type of device, the second type of device may each comprise a medium and/or a device capable of persistently storing information, and/or a tangible storage means. Accordingly, computer-readable storage media refers to non-signal bearing media. Computer-readable storage media include hardware such as volatile and nonvolatile, removable and non-removable media and/or storage devices implemented in a method or technology suitable for storage of information such as computer-readable instructions, data structures, program modules, logic elements/circuits, or other data.
Fig. 2 illustrates an exemplary flow diagram of a route configuration method 200 implemented at a first type of device according to some embodiments of the present application. The first type of device may be a first type of device as shown in fig. 1 and the second type of device may be a second type of device as shown in fig. 1. And each of the first type devices comprises a graphics processor, routing means for routing to a plurality of other first type devices and a port for communicating with other devices. As shown in fig. 2, the route configuration method 200 implemented at a first type of device may include steps S210-S240.
In step S210, port connection information between one first-type device and other first-type devices is obtained. In some embodiments, the first type of device may be a GPU card including a GPU chip, the GPU cards are interconnected through a port, and the port connection information may be information of the GPU card where the port is located and a port number of the port in the GPU card.
In step S220, the port connection information is sent to the second type device, so that the second type device determines routing information between the first type devices based on the port connection information. In some embodiments, the first type device may send the port connection information to the second type device through wired or wireless communication, for example, the port connection information may be sent to the second type device through a bus. By way of example, the second type of device may be a HOST device or other computing device. After receiving the port connection information, the second-class device determines routing information among the first-class devices based on the port connection information.
In step S230, routing information of a first type device communicating with other first type devices is obtained from a second type device. In some embodiments, the second type device may split the determined routing information into a plurality of parts according to the requirements of each first type device, and then send each part to the corresponding first type device. For example, in the application scenario shown in fig. 1, the second type device sends the routing information required by the first type device 0 to the first type device 0, and sends the routing information required by the first type device N to the first type device N. Thus, a first type device can obtain the routing information of the communication between itself and other first type devices from a second type device.
In step S240, the routing device is configured based on the routing information. In some embodiments, after the first type device receives the routing information required by itself from the second type device, the routing apparatus of itself will be configured based on this.
The method 200 first obtains port connection information between the first-type devices and sends the port connection information to the second-type devices, so that the second-type devices can determine routing information based on the port connection information between the first-type devices, and the routing information can sufficiently meet subsequent data transmission requirements between the first-type devices. And the method 200 configures the routing means of the first type devices based on the routing information so that the first type devices can communicate with each other based on the routing information.
In some embodiments, each of the first type devices includes a connection port, the connection port is connected to a connection port of another first type device, and acquiring port connection information between one first type device and another first type device includes: determining port information of connection ports connected to other first-class devices in one first-class device; acquiring port information of a docking port in other first-class devices, which is docked with the connection port; and determining port connection information based on the port information of the connection port and the port information of the docking port.
As an example, the first type of device may be a GPU card, and the connection port and the docking port may be ports of the GPU card that are connected to each other. For example, if port 3 of GPU card 1 is used as a connection port and port 1 of GPU card 2 is used as an interface port for interfacing with port 3 of GPU card 1, the port connection information may be "13-21". Here, "13" represents port 3 of GPU card 1, and "21" represents port 1 of GPU card 2.
In some embodiments, obtaining port information of a docking port that docks with the connection port in the other first-type device includes: indicating that a first type of device is ready to acquire information; and acquiring port information of the docking port where the other first-type device is docked with the connection port.
As an example, when a first type device indicates that it is ready to obtain information, other first type devices connected to it may send information of their docking ports that dock with the connection port of a first type device to a first type device. At this time, one first-type device may obtain port information of a docking port where the other first-type device docks with the connection port.
In some embodiments, the first type device further includes a first status register and a first information register, and a second status register and a second information register, the first status register is configured to store status information of the connection port, the first information register is configured to store port information of the connection port, the second status register is configured to store information stored by the first status register of the other first type device acquired from the docking port through the connection port, and the second information register is configured to store information stored by the first information register of the other first type device acquired from the docking port through the connection port.
In some embodiments, the communication between the first class of devices may be based on ILKN protocol, in which case the first status register may be an InitDone register, the first information register may be a Topoinfo register, the second status register may be an initdoneseshadow register, and the second information register may be a Topoinfo shadow register. For example, the first type of device may be a GPU card, where, based on the ILKN protocol, the GPU card has, for each connected port, an InitDone register, a Topoinfo register, an initdonoshadow register, and a Topoinfo shadow register, which are used for: recording whether a connection port is ready, recording port information of the connection port, recording whether a docking port is ready, and recording port information of the docking port. And the InitDoneShadow register and the TopoInfoShadow register of the connection port are respectively synchronized with the InitDone register and the TopoInfo register of the docking port.
In some embodiments, indicating that a first type of device is ready to obtain information comprises: storing a ready signal into a first status register of a first type of device for a connection port such that: the other first-class devices acquire the ready signals stored by the first status register from the connecting port through the docking port and store the ready signals into second status registers of the other first-class devices, and in response to the second status registers of the other first-class devices storing the ready signals, the other first-class devices store port information of the docking port into first information registers of the other first-class devices for the docking port.
As an example, the first type of device may be a GPU card, the connection port may be port 3 of GPU card 1, and the docking port may be port 1 of GPU card 2. The GPU card 1 and the GPU card 2 can handshake and communicate based on ILKN protocol. When the GPU card 1 indicates that it is ready to obtain information, it may store, for example, a character 1 or 2 in the InitDone register corresponding to the port 3, and at this time, the initdoneshedow register of the port 1 of the GPU card 2 will be automatically synchronized to 1 or 2.GPU card 2 may thus learn that GPU card 1 is ready to retrieve information.
In some embodiments, obtaining port information of a docking port where other first-type devices dock with the connection port includes: acquiring port information of the docking ports stored in the first information registers of other first-class devices from the docking ports docked with the connection ports through the connection ports; storing the port information of the docking port in a second information register of the first type device; and acquiring the port information of the docking port from a second information register of the first type device.
As an example, the first type of device may be a GPU card, the connection port may be port 3 of GPU card 1, and the docking port may be port 1 of GPU card 2. The GPU card 1 and the GPU card 2 can handshake and communicate based on ILKN protocol. When GPU card 2 learns that GPU card 1 is ready to fetch information, the port information for port 1 of GPU card 2 is stored in its Topoinfo register. This port information is then automatically synchronized by the hardware to the topoinfo shadow register of port 3 of GPU card 1. At this time, GPU card 1 will obtain the port information of the docking port from the TopoinfoShadow register of its port 3.
In some embodiments, the port information includes a device number of the first type device in which the port is located and a port number of the port in the first type device. For example, if the device number of a first type device is 3 and the port number of the connection port on this first type device is 5, the port information of the connection port is "35".
In some embodiments, the first type devices may be GPU cards, and the connection and communication between the first type devices may be based on ILKN and Serdes. The second type of device may be a HOST device. At this time, the performing the routing configuration on the first type device may include: training Serdes, ILKN initialization, handshaking and enumeration, reporting port connection information to HOST equipment, and the like.
As an example, the process of handshaking port 3 of GPU card 1 with port 1 of GPU card 2 will be described below. First, the GPU chip in the GPU card 1 will automatically boot the FW to run after being powered on, the FW will initialize Serdes, and then Serdes will be trained to meet the communication requirement between the GPU cards. Then, ILKN is initialized. When ILKN initialization is completed, 1 will be written in the InitDone register corresponding to port 3, indicating that the connection port can start communication. At this time, the contents of the initdoneshedow register of port 1 of GPU card 2 are also synchronized to 1.GPU card 2 thus knows that GPU card 1 is ready, writes the port information of the docking port that it is docked with GPU card 1 into the TopoInfo register. Alternatively, the written data may be in the format shown in table I.

At this time, the device number may be the number of the GPU card, and the port number may be the number of the port in the GPU card, which is reserved to indicate that these bits may be used for other functions. For example, FWs of nth first-class devices (n is a natural number) may write values as shown in table II to TopoInfo registers of different ports, respectively, to characterize port information.

In some embodiments, configuring the routing device based on the routing information comprises: determining routing ports of a first type device and other first type devices based on the routing information; determining address ranges of other first-type devices; mapping at least part of addresses in the address range of other first-type devices to the routing port; and configuring the mapped information to the routing device.
As an example, the routing port of one first type device and the other first type device may be connection ports therebetween. And when one first-class device is not directly connected with other first-class devices, the relay can be carried out through another or a plurality of other first-class devices.
In some embodiments, mapping at least part of the addresses within the address range of the other first type devices to the routing port comprises: determining an address set, wherein the address set comprises all addresses in the address range of other first-type devices; determining the number of routing ports between one first-class device and other first-class devices; averagely dividing the address set into a plurality of sub-address sets; respectively corresponding the number of sub-address sets to the routing ports; and establishing mapping between the addresses in the sub-address set and the routing ports corresponding to the sub-address set.
By way of example, the address range of one first-type device is 0-4G, the address ranges of other first-type devices are 4G-8G, and one first-type device is connected with other first-type devices through 4 ports. Alternatively, the four ports may be mapped to address ranges of 4G-5G, 5G-6G, 6G-7G, 7G-8G, respectively.
Fig. 3 illustrates an exemplary flow diagram of a route configuration method 300 implemented at a second class of devices according to some embodiments of the present application. As shown in fig. 3, the route configuration method 300 includes steps S310, S320, and S330.
In step S310, port connection information of a plurality of first-class devices is acquired. In some embodiments, the second type device may obtain port connection information of the plurality of first type devices from the plurality of first type devices by means of wired communication or wireless communication. For example, the second type device may obtain port connection information from a plurality of first type devices through the bus.
In step S320, routing information between the plurality of first type devices is determined based on the port connection information. In some embodiments, the second type device may determine a topology structure between the plurality of first type devices based on the port connection information, and then determine routing information between the plurality of first type devices according to the structure.
In step S330, the routing information is sent to the plurality of first type devices, so that each of the plurality of first type devices configures its routing apparatus based on the routing information. In some embodiments, the second type device may divide the determined routing information into a plurality of portions according to the own requirements of each first type device, each portion being applicable to one first type device, and send each portion to the corresponding first type device to configure its routing apparatus. For example, for the scenario shown in FIG. 1, the second type device may send the routing information required by the first type device N to the first type device N based on the requirement of the first type device N (0 ≦ N ≦ N).
In the method 300, the second type device determines the routing information between the first type devices based on the port connection information between the first type devices, so that the routing information can sufficiently meet the subsequent data transmission requirements between the first type devices. And after determining the routing information among the first-class devices, the second-class device sends the routing information to the first-class devices, so that the first-class devices can configure their own routing devices based on the routing information, and then communicate with each other based on the routing information.
In some embodiments, determining routing information between the plurality of first class devices based on the port connection information comprises: determining a topology structure among a plurality of first-class devices based on the port connection information; determining candidate routes among a plurality of first-class devices based on the topology; determining a shortest route between the plurality of first class devices based on the candidate routes; and determining routing information between the plurality of first type devices based on the shortest route. This will be described in detail below by way of example.
As an example, fig. 4 shows a schematic diagram of port connection information for a plurality of first type devices according to some embodiments of the present application. As shown in fig. 4, 8 devices of the first type are connected by ports. It is noted that the first type of device in the figure is still in communication with the second type of device, but is not shown.
First, each of a plurality of first-class devices acquires port connection information between itself and other first-class devices. Alternatively, the port connection information may be represented using the data formats shown in table III and table IV. For example, the first type device 0 obtains port connection information between itself and the first type device 1: 03-10 and 04-11.
Then, each of the plurality of first type devices transmits the port connection information to the second type device. Optionally, each of the plurality of first type devices may send a table in the data format of table III and table IV to the second type device.
Then, the second-class device acquires port connection information of the plurality of first-class devices and determines routing information among the plurality of first-class devices based on the port connection information. First, the second type device will determine the topology between the plurality of first type devices based on the port connection information. Fig. 5 shows, as an example, a schematic diagram of a topology determined by a second type device based on port connection information between a plurality of first type devices in fig. 4.
As shown in fig. 5, the numbers in the circles in the figure represent the numbers of the first type devices, and the lines between the circles represent candidate routes, which may be represented by alphabets in combination with the numbers. For example q (23-30) indicates that port 3 of the first type device 2 is connected to port 0 of the first type device 3.
The second class device will then determine a candidate route between the plurality of first class devices based on the topology and determine the shortest route between the plurality of first class devices based on the candidate route. As can be seen from fig. 5, the first type device 0 and the first type device 4 may communicate with each other via a plurality of candidate routes. To this end, the second type device may determine a candidate route between the plurality of first type devices and determine the shortest route between the plurality of first type devices based on the candidate route. For example, a classic data structure algorithm may be used to calculate the shortest path between every two first-type devices, where the shortest path may not be one, and in some embodiments, when there are multiple shortest paths, load balancing may be performed, and the shortest optimal path may be selected in combination with the load balancing. Specifically, based on the topology shown in fig. 5, the determined shortest path between the first type devices is shown in table V.

As shown in Table V, "number" represents the number of the first type device, and the letter in the table represents the shortest route between the first type devices. The second class of devices will then determine routing information between the plurality of first class devices based on the shortest route.
The second class device then sends the routing information to the plurality of first class devices to cause each of the plurality of first class devices to configure its routing means based on the routing information. As an example, when the routing information is sent, the complete routing information is sent, for example, mn in the table is supplemented as m (03-10) n (04-11) to be sent.
Finally, each first-class device of the plurality of first-class devices acquires the routing information of the first-class device communicating with other first-class devices from the second-class device, and configures the routing device based on the routing information.
For example, when the first type of device is a GPU card and the second type of device is a HOST device, the FW of each GPU card receives the routing data from the HOST device and then configures the routing device accordingly according to the routing data. As an example, table 6 shows routing data sent by the HOST device to GPU card 0.

As shown in table VI, the numbers indicate the numbers of the first type devices and the letters represent routing paths. Specifically, m refers to m (03-10), which represents that port 3 of the first type device 0 and port 0 of the first type device 1 are interconnected; n refers to n (04-11), which represents that the port 4 of the first type device 0 is interconnected with the port 1 of the first type device 1; o refers to O (13-20) and represents that port 3 of the first type device 1 and port 0 of the first type device 2 are interconnected; p refers to p (14-21) indicating that port 4 of the first type device 1 and port 1 of the first type device 2 are interconnected; e refers to e (12-60) indicating that port 2 of the first type device 1 and port 0 of the first type device 6 are interconnected; f refers to f (15-63) indicating that port 5 of the first type device 1 and port 3 of the first type device 6 are interconnected; a refers to a (00-72), which indicates that port 0 of the first type device 0 and port 2 of the first type device 7 are interconnected; b refers to b (01-71), which represents the interconnection of port 1 of the first type device 0 and port 1 of the first type device 7; c refers to c (02-70), which represents the interconnection of port 2 of first class device 0 and port 0 of first class device 7; d refers to d (05-73) and indicates that port 5 of device 0 of the first type and port 3 of device 7 of the first type are interconnected.
At this time, the first device 0 configures its routing means based on the route existence data shown in table VI. Specifically, the method comprises the following steps: determining a set of addresses comprising all addresses within the address range of the other first type devices, e.g. in the embodiment shown in fig. 4, the set of addresses comprises addresses of eight first type devices; determining the number of routing ports between one first type device and other first type devices, e.g., in the embodiment shown in fig. 4, the number of routing ports between the first type device and other first type devices is 6; averagely dividing the address set into a plurality of sub-address sets; respectively corresponding the number of sub-address sets to the routing ports; and establishing a mapping between addresses in the sub-address set and routing ports corresponding to the sub-address set, which may be specifically shown in fig. 6.
FIG. 6 illustrates a schematic diagram of address mapping according to some embodiments of the present application. As shown in fig. 6, device 0 of the first type maps addresses to video memory or ports. Specifically, addresses for different ranges will be mapped to either the video memory or one of the ports. The specific mapping information of the address mapping shown in fig. 6 is applicable to the first type device 0 of the connected first type devices shown in fig. 4. And the address mapping method shown in fig. 6, is suitable for any first type device. In the first type device shown in fig. 6, the video memory of the first type device is 64G, so when the address is 0-64G, the first type device 0 will map the address to its video memory, and when the address exceeds 64G, the port will be called for.
In addition, a system for routing configuration is disclosed, comprising a plurality of first type devices and a second type device, each of the plurality of first type devices comprising a graphics processor, routing means for routing to a plurality of other first type devices and a port for communicating with other devices, the system comprising: each first-class device of the plurality of first-class devices acquires port connection information of the first-class device and other first-class devices; each first-class device of the plurality of first-class devices sends port connection information to the second-class device; the second-class equipment acquires port connection information of a plurality of first-class equipment; the second type equipment determines routing information among the first type equipment based on the port connection information; the second-class device sends the routing information to the plurality of first-class devices, so that each first-class device of the plurality of first-class devices configures a routing device of the first-class device based on the routing information; each first-class device of the plurality of first-class devices acquires routing information of communication between the first-class device and other first-class devices from the second-class device; and each of the plurality of first type devices configures its routing means based on the routing information.

It can be seen that, in the system for route configuration disclosed in the present application, first, a plurality of first-class devices obtain port connection information between themselves and other first-class devices and upload the port connection information to a second-class device, and the second-class device determines, based on the port connection information between the first-class devices, route information between the first-class devices, so that the route information can sufficiently meet subsequent data transmission requirements between the first-class devices. The second type device then sends the routing information to the plurality of first type devices. Finally, each first-class device configures the routing device based on the routing information, so that each first-class device can communicate with each other based on the routing information.
