Hi,
We've been using GrpCPURunMins as our primary user limit quite
successfully for a few years now. Lately there's been a need to also
limit the amount of memory an account can allocate at one time. I use
GrpCPURunMins to say something like "you can use 1/4 of the cluster for
one day, or all of the cluster for 1/4 of a day". But with memory it
seems I am limited to a hard number, say 1/4 of the cluster without
respect to the duration of the allocation.
We're running 18.08, although moving to 20.02 is likely in the near
future. This is a small cluster (50ish nodes), and nodes are not
allocated exclusively to a job.
The documentation only refers to GrpGRESRunMins, but I can't figure out
what I might substitute for GRES that means Memory in the same way that
substituting CPU means, well, CPUs. Google turns up precisely nothing
for GrpMemRunMins... Am I missing something?
Thanks!
Corey
