[slurm-users] Slurm 17.11 and configuring backfill and oversubscribe to allow concurrent processes

[Renfro, Michael]

If that 32 GB is main system RAM, and not GPU RAM, then yes. Since our GPU nodes are over-provisioned in terms of both RAM and CPU, we end up using the excess resources for non-GPU jobs.

If that 32 GB is GPU RAM, then I have no experience with that, but I suspect MPS would be required.
