GPU box PCIE extended interconnection topology device

Abstract

The invention discloses a GPU box PCIE extended interconnection topology device. The device comprises a GPU box, wherein the GPU box comprises eight groups of interconnected GPUs, a CPU server connected with the GPUs and a PCIE switch module; the PCIE switch module installs a high-speed interconnected cable card through a PCIE slot to realize interconnection among different GPU boxes; the GPUs areconnected through the PCIE switch module; the CPU server is connected with the GPU box through a PCIE link; the PCIE switch module extends the PCIE link into eight groups of PCIE X16 links to realizeconnection between the CPU server and the eight groups of GPUs. Through the device, independent design of a standard PCIE interface GPU box is realized, maximization of GPU performance is guaranteed,transmission delay is short, extensibility is good, flexible configuration and matching usage can be realized, and GPU box design needed for high performance and artificial intelligence is provided.

Description

technical field [0001] The invention relates to the technical field of server board design, in particular to a GPU box PCIE extended interconnection topology device. Background technique [0002] With the rise of artificial intelligence and high-performance computing, the advantages of GPU (Graphics Processor Unit display processor unit) computing are becoming more and more obvious in high-performance computers. Compared with traditional CPU processors, ultra-high output cores, More suitable for artificial intelligence and high-performance requirements for more parallel computing, GPU servers have become the next rapid growth point of servers. [0003] The current GPU design basically adopts the universal PCIE (peripheral component interconnect express high-speed serial computer expansion bus) slot interface, which is basically integrated into the server, bound to the server itself, and sold as a GPU server or high-performance server. The standard PCIE interface is a common...

Problems solved by technology

The standard PCIE interface is a common design method for general-purpose servers, but because GPU design requires more power and structural space, when the server itself only has a single GPU, the design is no problem, but it is applied to artificial intelligence and high-performance servers. Now more GPU processors need to be used. The multi-GPU design will make the server larger, and the compatibility with other standard card designs is not good. Similarly, the PCIE structure will become the bottleneck of data exchange processing between GPUs, which is serious. Affect the performance of multiple GPUs under the multi-GPU architecture

[0004] The integrated design of GPU and CPU processors binds the
