General

If you have a job that is running on a GPU node and that is expected to use a GPU on that node, you can check the GPU use by your code by running the following command on ARC's login node:

$ srun -s --jobid 12345678 --pty nvidia-smi

The number here is the job ID of the running job.

The output should look similar to the following:

+-----------------------------------------------------------------------------+

In this case there was 1 GPU allocated and its usage was 30%. The code openDBA also uses 338 MB of the GPU memory.
