[slurm-users] 19.05 and GPUs vs GRES

[Barbara Krašovec]

We have SLURM 19.05. and implemented the cons_tres scheduling type.

It does work only by specifying the --gpus-per-node when submitting the
job. And there are many more options.

I found this presentation to be quite informative:
https://slurm.schedmd.com/SLUG18/cons_tres.pdf

We still have the gres configuration, users have their workload scripted
and some still use sbatch with gres. Both options work.

Cheers,

Barbara
