Running the Pre-flight Test

Instructions for running the DGX stress test.

NVIDIA recommends running the pre-flight stress test before putting a system into a production environment or after servicing. You can specify running the test on the GPUs, CPU, memory, and storage, and also specify the duration of the tests.

To run the tests, use NVSM.


$ sudo nvsm stress-test [--usage] [--force] [--no-prompt] [<test>...] [DURATION] 

For help on running the test, issue the following.

~$ sudo nvsm stress-test --usage 

Recommended Command

The following command runs the test on all supported components (GPU, CPU, memory, and storage), and takes approximately 20 minutes.

~$ sudo nvsm stress-test --force
