Abstract

The embodiment of the present invention discloses a SXM2 GPU link test board and a test method. The test board includes a card connector, a power conversion module, a PCIE slot and an NV LINK module. The card connector is used to connect to a GPU server , the power conversion module is used to supply power to the test board, the PCIE slot is installed with a PCIE GPU card to verify whether the PCIE link connected to the SXM2 GPU is normal, and the NV LINK module is used to test the connection between the SXM2 GPUs The link is normal. The present invention does not need to use a real SXM2 GPU module to test the reliability of the link of the SXM2 GPU module, avoids damage to the SXM2 GPU module during the link test, and greatly saves the test cost.

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...
