Before describing embodiments of the present application in detail, concepts of routing and related techniques are explained first.

Route (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 an IP subnet or point-to-point protocol, having at least 1 physical port. The router decides the output port and the next hop address according to the network layer address in the received data packet and the routing table maintained in the router, and rewrites the link layer data packet header to realize the forwarding of the data packet. The router reflects the current network topology by dynamically maintaining a routing table and maintains the routing table by exchanging routing and link information with other routers on the network.

GPU (graphics processing unit): namely, a graphic processor, also called a display core, a visual processor, a display chip, is a microprocessor which is specially used for performing image and graphic related operation on a personal computer, a workstation, a game machine and some mobile devices (such as a tablet computer, a smart phone and the like).

And (3) video memory: the video memory, also called frame buffer, is used to store rendering data that has been processed or is to be extracted by the graphics card chip. As with the memory of a computer, a video memory is a means for storing graphic information to be processed.

Communication protocol: a communication protocol refers to rules and conventions that must be followed by two parties to an entity to complete a communication or service.

Interlaken: also known as ILKN, is a protocol for high-speed data transmission between chips.

Serdes: SERDES, also known as SERializer/DESerializer, is also known. It is a mainstream Time Division Multiplexing (TDM), point-to-point (P2P) serial communication technology. The multi-path low-speed parallel signals are converted into high-speed serial signals at the transmitting end, and finally the high-speed serial signals are converted into low-speed parallel signals at the receiving end 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 piece of program running on the SMC.

InitDone register: one register used in the ILKN protocol, into which the value written is automatically synchronized into the InitDoneShadow register of the docking port. The InitDone register is used to prepare for port handshakes. Typically, there is one InitDone register per port.

The InitDoneShadow register: one register used in the ILKN protocol, the value of which will follow the change in the value of the InitDone register of the docking port. Typically, there is one InitDoneShadow register per port.

TopoInfo register: a register used in ILKN protocol may be written with a 64bits of data that is automatically synchronized by hardware to the TopoInfoShadow register of the docking port. Typically, there is one TopoInfo register per port.

TopoInfoShadow register: a register used in the ILKN protocol whose value varies with the value of the docking port TopoInfo register. Typically, there is one TopoInfoShadow register per port.

Host device: also referred to as a host computer, may be a host computer or the like. When communication of a plurality of terminals is performed, processing by a host is required.

Topology structure: topology refers to the physical layout of various devices such as computers interconnected by a transmission medium, and refers to the geometry formed during the interconnection process, which represents the network configuration of the network servers, workstations, and interconnections.

Fig. 1 illustrates an exemplary application scenario of a route configuration method according to some embodiments of the application. As shown in fig. 1, the application scenario may include at least one second type device and a plurality of first type devices. Devices of the first type may be interconnected and communicate via ports. And the first type of device may communicate with the second type of device by way of wired or wireless communication, such as by way of a bus. The first type of device may be a computing device such as a GPU card. 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 includes a graphics processor, routing means for routing to a plurality of other first type devices, and ports for communicating with the other devices. The method for routing configuration implemented at a first class of devices includes: acquiring port connection information of one first type of equipment and other first type of equipment; transmitting the port connection information to the second class of devices, so that the second class of devices determine routing information among the first class of devices based on the port connection information; obtaining route information of communication between a first type device and other first type devices from a second type device; and configuring the routing means of the first class of devices based on the routing information.

It should be noted that fig. 1 shows only an exemplary embodiment of an application scenario. The number of the first type devices, the number of the second type devices, the number of ports of the first type devices, the connection relationship between the first type devices, and the like can be changed according to different application scenarios, and the method is not limited herein. And the second type device and the first type device may be connected by a common connection manner, including but not limited to a wired connection, a wireless connection, etc., for example, through a bus, 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 device capable of persistent storage of information, and/or a tangible storage means. Thus, 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 methods or techniques 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 chart of a route configuration method 200 implemented at a first type of device according to some embodiments of the 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 includes a graphics processor, routing means for routing to a plurality of other first type devices, and a port for communicating with the 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 of 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 GPU chips, where the GPU cards are interconnected by ports, and the port connection information may be information of the GPU card where the ports are located and port numbers of the ports in the GPU card.

In step S220, port connection information is transmitted to the second class of devices, so that the second class of devices determine routing information between the respective first class of devices based on the port connection information. In some embodiments, the first type of device may send the port connection information to the second type of device by way of wired or wireless communication, e.g., the port connection information may be sent to the second type of device via a bus. As an example, the second type of device may be a HOST device, or may be another computing device. After receiving the port connection information, the second type devices determine routing information between the first type devices based on the port connection information.

In step S230, route information for one first type device to communicate with other first type devices is acquired from the second type device. In some embodiments, the second type device splits the determined routing information into a plurality of parts according to the requirements of each first type device, and then sends each part to the corresponding first type device. For example, in the application scenario shown in fig. 1, the second type device may send routing information required by the first type device 0 to the first type device 0, and send routing information required by the first type device N to the first type device N. Thus, one first type device may obtain from a second type device routing information that itself communicates with other first type devices.

In step S240, the routing device is configured based on the routing information. In some embodiments, after the first type of device receives the routing information required by itself from the second type of device, the routing device of itself will be configured based thereon.

The method 200 firstly obtains port connection information between the first-class devices and sends the port connection information to the second-class devices, so that the second-class devices can determine routing information based on the port connection information between the first-class devices, and the routing information can fully meet subsequent data transmission requirements between the first-class devices. And, the method 200 configures the routing means of the first class devices based on the routing information, so that the first class devices may 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 interfacing with an interfacing port of another first type device, and obtaining port connection information of one first type device with the other 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 butt joint port which is in butt joint with a connection port in other first-class equipment; 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 mutually connected GPU cards. For example, port 3 of GPU card 1 is used as a connection port, port 1 of GPU card 2 is used as a docking port for docking with port 3 of GPU card 1, and 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 a connection port in other first class devices includes: indicating that a first type of device is ready to obtain information; and acquiring port information of a butt joint port of other first-class equipment and the connection port.

As an example, when a first type device indicates itself to be ready to acquire information, other first type devices connected thereto may send information of a docking port to which the connection port of the first type device is docked to the first type device. At this time, one first type device may acquire port information of a docking port where the other first type device docks with the connection port.

In some embodiments, the first type of device further comprises a first status register for storing status information of the connection port, a first information register for storing port information of the connection port, and a second status register for storing information stored in the first status register of the other first type of device acquired from the docking port through the connection port, and a second information register for storing information stored in the first information register of the other first type of device acquired from the docking port through the connection port.

In some embodiments, the communication between the first type of devices may be based on ILKN protocol, where 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 InitDoneShadow register, and the second information register may be a Topoinfo shadow register. For example, the first type of device may be a GPU card, in which case, based on the ILKN protocol, the GPU card has for each connected port an InitDone register, a Topoinfo register, an InitDoneShadow register, a Topoinfo shadow register, respectively: recording whether the connection port is ready, recording port information of the connection port, recording whether the 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 in content synchronization 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 includes: storing the ready signal in a first status register for the connection port of a first type of device such that: the other first type device obtains a readiness signal stored by the first status register from the connection port via the docking port and stores the readiness signal into a second status register of the other first type device, and in response to the second status register of the other first type device storing the readiness signal, the other first type device stores port information of the docking port into a first information register of the other first type device 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.GPU card 1 and GPU card 2 may handshake and communicate based on the ILKN protocol. When GPU card 1 is to indicate that it is ready to acquire information, it may store a character, e.g., 1 or 2, into the InitDone register corresponding to port 3, at which point the InitDoneShadow register of port 1 of GPU card 2 will be automatically synchronized to 1 or 2.GPU card 2 may thus learn that GPU card 1 is ready to acquire information.

In some embodiments, obtaining port information of a docking port for docking other first class devices with a connection port includes: obtaining port information of the docking port stored in a first information register of other first type equipment from the docking port docked with the connection port through the connection port; storing port information of the docking port in a second information register of the first type of equipment; and obtaining port information of the docking port from a second information register of the first type of equipment.

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.GPU card 1 and GPU card 2 may handshake and communicate based on the ILKN protocol. When GPU card 2 learns that GPU card 1 is ready to acquire information, port information for port 1 of GPU card 2 is stored in its Topoinfo register. The port information is then automatically synchronized by the hardware to the topoinfo shadow register of port 3 of GPU card 1. At this point, GPU card 1 will obtain port information for the docking port from its TopoinfoShadow register for port 3.

In some embodiments, the port information includes a device number of a first type of device in which the port is located and a port number of the port in the first type of device. For example, if the device number of a first type device is 3 and the port number of the connection port at this first type device is 5, the port information of the connection port is "35".

In some embodiments, the first type of device may be a GPU card and the connections and communications between the first type of devices may be based on ILKN and Serdes. The second type of device may be a HOST device. At this time, the routing configuration for the first type of device may include: training Serdes, ILKN initialization, handshaking and enumeration, reporting port connection information to HOST devices, and the like.

By way of example, the process of port 3 of GPU card 1 handshaking with port 1 of GPU card 2 will be described below. Firstly, the GPU chip in the GPU card 1 will automatically guide FW to run after being powered on, the FW will initialize Serdes, and the Serdes will train 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 InitDoneShadow register of port 1 of GPU card 2 will also be synchronized 1.GPU card 2 thus knows that GPU card 1 is ready to write port information of the docking port itself docked with GPU card 1 into the TopoInfo register. Alternatively, the written data may be selected in the format shown in table I.

Table I data format

bits	Meaning of
		0-16	Device numbering
16-24	Port numbering
		24-63	Reservation of

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

Table II characterizes the values of the port information

Port numbering	Values characterizing port information

		2	0x02<<16|n
3	0x03<<16|n
		4	0x04<<16|n
5	0x05<<16|n

The GPU card will then report port connection information to the HOST device. As an example, port connection information may be characterized by the data shown in tables III and IV.

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 chart of a route configuration method 300 implemented at a second class of devices according to some embodiments of the application. As shown in fig. 3, the route configuration method 300 includes step S310, step S320, and step 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 way of wired communication or wireless communication. For example, the second type device may obtain port connection information from a plurality of first type devices via a bus.

In step S320, routing information between a plurality of first type devices is determined based on the port connection information. In some embodiments, the second type device may determine a topology 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 based on the topology.

In step S330, the routing information is sent to the plurality of first-type devices, such that each of the plurality of first-type devices configures its routing means 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 requirements of the respective first type device itself, each portion being adapted for one first type device, and send the respective portion to the corresponding first type device to configure its routing means. For example, for the scenario shown in FIG. 1, a second type device may send routing information needed by a first type device N to the first type device N based on the requirements of the first type device N (0N N).

In method 300, the second type devices determine routing information between the first type devices based on the port connection information between the first type devices, which enables the routing information to fully satisfy subsequent data transmission requirements between the first type devices. And the second type device sends the routing information to the plurality of first type devices after determining the routing information among the first type devices, so that the plurality of first type devices can configure own routing devices based on the routing information so as to communicate with each other based on the routing information.

In some embodiments, determining routing information between a plurality of first type devices based on port connection information includes: determining a topology between a plurality of first class devices based on the port connection information; determining candidate routes between 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 class devices based on the shortest route. This will be described in detail 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 application. As shown in fig. 4, 8 first type devices are connected through ports. It should be noted that the first type of device is still in communication with the second type of device in the figures, but is not shown.

First, each first-type device of the plurality of first-type devices acquires port connection information of the first-type device and other first-type devices. Alternatively, the port connection information may be represented using the data formats shown in tables III and IV. For example, the first type device 0 acquires port connection information between itself and the first type device 1: 03-10, 04-11.

Each of the plurality of first type devices then transmits port connection information to the second type device. Alternatively, each of the plurality of first type devices may send a table, such as table III and table IV data formats, to the second type device.

Then, the second type device acquires port connection information of the plurality of first type devices and determines routing information between the plurality of first type 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. As an example, fig. 5 shows a schematic diagram of a topology structure determined by a second type device based on port connection information among 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 of devices, and the links between the circles represent candidate routes, which may be indicated by letter-to-number. 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 type device will then determine candidate routes between the plurality of first type devices based on the topology and determine a shortest route between the plurality of first type devices based on the candidate routes. As can be seen from fig. 5, communication between the first class device 0 and the first class device 4 may be via a variety of candidate routes. To this end, the second type device may determine candidate routes between the plurality of first type devices and determine a shortest route between the plurality of first type devices based on the candidate routes. For example, a classical data structure algorithm may be used to calculate the shortest path between every two first class 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 load balancing. Specifically, based on the topology shown in fig. 5, the shortest path between the first type of devices is determined as shown in table V.

As shown in table V, "number" indicates the number of the first type of device, and the letters in the table indicate the shortest route between the first type of devices. The second type device will then determine routing information between the plurality of first type devices based on the shortest route.

The second type device then transmits the routing information to the plurality of first type devices such that each of the plurality of first type devices configures its routing means based on the routing information. As an example, when routing information is sent, complete routing information is sent, e.g. mn in the table is supplemented with m (03-10) n (04-11) for sending.

Finally, each of the plurality of first-type devices obtains from the second-type device its own routing information for communication with the other first-type devices, and configures its routing means 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 according to the routing data. As an example, table 6 shows routing data sent by HOST device to GPU card 0.

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 means that port 4 of the first class device 0 and port 1 of the first class device 1 are interconnected; o means O (13-20) indicating that port 3 of the first type device 1 and port 0 of the first type device 2 are interconnected; p denotes 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 denotes 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 denotes 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) indicating that port 0 of device 0 of the first type and port 2 of device 7 of the first type are interconnected; b denotes b (01-71) indicating that port 1 of the first type device 0 and port 1 of the first type device 7 are interconnected; c denotes c (02-70) indicating that port 2 of the first type device 0 and port 0 of the first type device 7 are interconnected; d denotes d (05-73) indicating 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 class device 0 configures its routing means based on the route data shown in table VI. Specifically, the method comprises the following steps: determining an address set comprising all addresses within the address range of the other first type devices, e.g. in the embodiment shown in fig. 4, the address set comprises the addresses of eight first type devices; determining a number of routing ports between one first type device and the other first type device, e.g. in the embodiment shown in fig. 4, the number of routing ports between the first type device and the other first type device is 6; dividing the address set into a plurality of sub-address sets on average; respectively corresponding the number of sub-address sets with the routing ports; and mapping is established between the addresses in the sub-address set and the routing ports corresponding to the sub-address set, specifically, as shown in fig. 6.

FIG. 6 illustrates a schematic diagram of address mapping according to some embodiments of the application. As shown in fig. 6, the first class of devices 0 map addresses to memory or ports. Specifically, for different ranges of addresses, mapping to memory or one of the ports will occur. The specific mapping information of the address mapping shown in fig. 6 is applicable to the first type device 0 among the connected first type devices shown in fig. 4. And, the address mapping method shown in fig. 6 is applicable to any first type of device. In the first type of device shown in fig. 6, the memory of the first type of device is 64G, so that when the address is 0-64G, the first type of device 0 maps the address to its own memory, and when the address exceeds 64G, the port is complained.

In addition, a system for routing configuration is disclosed, including a plurality of first-type devices and a second-type device, each of the plurality of first-type devices including a graphics processor, routing means for routing to a plurality of other first-type devices, and ports for communication with the other devices, the system comprising: each first type device of the plurality of first type devices acquires port connection information of the first type device and other first type devices; each of the plurality of first class devices transmitting port connection information to the second class device; the second type equipment acquires port connection information of a plurality of first type equipment; the second type device determines routing information among the plurality of first type devices based on the port connection information; the second class device sending routing information to the plurality of first class devices such that each of the plurality of first class devices configures its routing means based on the routing information; each first type device of the plurality of first type devices obtains routing information of itself communicating with other first type devices from the second type device; and each of the plurality of first-type devices configures its routing means based on the routing information.

As an example, the system of routing configurations may be arranged as shown in fig. 1, e.g. the devices of the first type may be connected by ports, the devices of the second type may be connected by wires or wirelessly, e.g. by bus connections, etc.

In the system for route configuration disclosed by the application, firstly, the plurality of first-class devices acquire port connection information of the first-class devices and other first-class devices and upload the port connection information to the second-class devices, and the second-class devices determine the route information among the first-class devices based on the port connection information among the first-class devices by the second-class devices, so that the route information can fully meet subsequent data transmission requirements among the first-class devices. The second type device then transmits the routing information to the plurality of first type devices.
