Embodiment 1

[0052] This embodiment provides a method for testing a GPU, such as figure 2 shown, methods include:

[0053] S210, receiving voltage data corresponding to each GPU power rail terminal sent by the data collector; the GPUs include: all GPUs included in the server to be tested;

[0054] When the server to be tested is powered on and enters the (BIOS, Basic Input / Output System) state, the host computer controls the server to be tested to run the EDPp script under BIOS, and the host computer sends data acquisition instructions to the data collector, and the data collector starts Collect the voltage data corresponding to each GPU power rail terminal, and send the collected voltage data to the host computer, then the host computer can receive the voltage data corresponding to each GPU power rail terminal sent by the data collector; the GPU includes: Test all GPUs included in the server.

[0055] For example, if there are 4 GPUs in the server to be tested, and each GPU has two Pow...

Embodiment 2

[0089] This embodiment provides a system for testing GPUs, such as figure 1 As shown, the system includes: a host computer 1, a data collector 2, a processor 3, an oscilloscope 4, and a server to be tested 5; wherein, the server to be tested 5 includes multiple GPUs; wherein,

[0090] The data collector 2 is used for voltage data corresponding to each GPU power rail terminal in a preset collection period, and sends the voltage data to the host computer 1;

[0091] The host computer 1 is used for receiving the voltage data corresponding to each GPU power rail terminal sent by the data collector; determining the first voltage value and the second voltage value corresponding to each power rail terminal; determining the maximum voltage value according to each first voltage value , and obtain the first power rail terminal corresponding to the maximum voltage value; determine the minimum voltage value according to each second voltage value, and obtain the second power rail terminal ...

Abstract

The present invention provides a method and system for testing the GPU, including: receiving voltage data corresponding to each GPU power rail end; determining the first voltage value and second voltage value of the corresponding power rail end;One voltage value determines the maximum voltage value, and obtains the first power rail with a maximum voltage value; determines the minimum voltage value according to the second voltage value of each second voltage, and obtains the second power rails corresponding to the minimum voltage value; control the first power rail; control the first power railThe terminal and the second power rail end is the direction state; sends a test instruction to the server to be tested to receive the test results; in this way, the maximum voltage value and the minimum voltage may exist at the same power rail end in the same GPU, or it may also be possibleExisting the power rails corresponding to different GPUs; therefore improve the reliability of testing and ensure test accuracy.

Description

technical field [0001] The invention belongs to the technical field of server testing, and in particular relates to a method and a system for testing a GPU. Background technique [0002] As the popularity of artificial intelligence continues to rise, the market demand for AI servers is gradually increasing. Graphics Processing Unit (GPU), as the core computing module of the server, plays an indispensable role in the AI ​​server. The GPU test can't be ignored either. EDPp is a kind of GPU stress script, which is mainly used to perform EDPp certification test on GPU to test the actual running performance of GPU. [0003] In the prior art, when performing an EDPp certification test on a GPU, because there are generally multiple GPUs, in order to improve the test efficiency, a worst GPU (called a Worst Case) is generally selected based on experience, and the test line is connected to the Worst Case. For each Power Rail terminal of the power rail to be tested, connect the respe...
