General
For Running Jobs
using SLURM
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.
For Past Jobs
Using Sampled Metrics
On the OOD portal, here https://ood-arc.rcs.ucalgary.ca login using your UofC credentials (it may require your full UofC email address instead of just user name).
Once you log in,
- Select Help --> View my job metrics,
- this will open an interface to your past jobs that are available in the database.
- Find the job you want to check and there may be useful graphs for GPU usage.
