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.
