Embodiment 1

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

[0053] S210, receiving the voltage data corresponding to each GPU power rail terminal sent by the data collector; the GPU includes: 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 the BIOS, and at the same time the host computer sends a data acquisition command to the data collector, and the data collector starts Collect the voltage data corresponding to each GPU power rail end, 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 end sent by the data collector; the GPU includes: All GPUs included in the test server.

[0055] For example, if there are 4 GPUs in the server to be tested, and...

Embodiment 2

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

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

[0091] The upper computer 1 is used to receive the voltage data corresponding to each GPU power rail end sent by the data collector; determine the first voltage value and the second voltage value corresponding to each power rail end; determine the maximum voltage value according to each first voltage value , and obtain the first power rail end corresponding to the maximum voltage value; determine the minimum voltage value according to each second voltage value, and obtain the second power rail end corresponding to the minimum volt...

Abstract

The invention provides a method and a system for testing GPUs (Graphics Processing Units). The method comprises the following steps: receiving voltage data corresponding to power rail ends of the GPUs; determining a first voltage value and a second voltage value corresponding to each power rail end; determining a maximum voltage value according to each first voltage value, and obtaining a first power supply rail end corresponding to the maximum voltage value; determining a minimum voltage value according to each second voltage value, and obtaining a second power supply rail end corresponding to the minimum voltage value; controlling the first power supply rail end and the second power supply rail end to be in a conducting state; sending a test instruction to the to-be-tested server, and receiving a test result; in this way, the maximum voltage value and the minimum voltage value may exist at the same power rail end in the same GPU and may also exist at the power rail ends correspondingto different GPUs. Therefore, the test reliability is improved and the test precision is ensured.

Description

technical field [0001] The invention belongs to the technical field of server testing, and in particular relates to a method and system for testing GPUs. Background technique [0002] As the popularity of the field of artificial intelligence continues to rise, the market demand for AI servers is gradually increasing. As the core computing module of the server, the graphics processing unit (GPU, Graphics Processing Unit) plays an indispensable role in the AI ​​server. GPU testing cannot be ignored either. EDPp is a kind of GPU stress script, which is mainly used for EDPp certification test on GPU to test the actual running performance of GPU. [0003] In prior art, when carrying out EDPp authentication test to GPU, because GPU generally comprises a plurality of, in order to improve test efficiency, generally be to select a worst GPU (called Worst Case) according to experience, test line is connected in Worst Case. For each Power Rail terminal of the power rail to be tested ...
