Abstract

The embodiment of the invention discloses an SXM2 GPU link test board card and method. The test board card comprises a card buckle connector, a power supply changeover module, a PCIE slot and an NV LINK module, wherein the card buckle connector is used for being connected with a GPU server, the power supply changeover module is used for supplying power to the test board card, the PCIE slot where aPCIE GPU card is installed is used for verifying whether or not a PCIE link connected with SXM2 GPUs is normal or not, and the NV LINK module is used for testing whether or not the link between the SXM2 GPUs is normal or not. When the SXM2 GPU link test board card and method are used for testing the reliability of the SXM2 GPU module link, it is unnecessary to use real SXM2 GPU modules for testing, damage caused to SXM2 GPU modules in the link test process is avoided, and the test cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of GPU servers, in particular to an SXM2 GPU link test board and a test method. 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 processors The core is more suitable for parallel computing artificial intelligence and high-performance requirements. GPU servers have become the next rapid growth point of servers. SXM2 (a high-performance processor module type defined by NVIDIA, a display processor company) , a high-spec GPU module independently defined by the original PCIE (peripheral component interconnect express, high-speed serial computer expansion bus) graphics card specification. [0003] For the SXM2 GPU server, in order to ensure the quality and perfor...
