[slurm-users] GrpMEMRunMins equivalent?

[Corey Keasling]

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
