Hi I'm new to Slurm, how do I set a default maximum CPU and GPU limit
per user?
We use GrpCPUs if set on the user (not the account) it's a per user
limit. We do similar with ram using GrpMEM. If you want a limit per
user * partition we use a QoS with GrpMEM/GrpCPUs limits.
I've not tried limiting GPUs, I can see why you'd want to though.
Actually my goal is to set a maximum CPU/hour per user, in a way that
one user can use a maximum value calculated by (CPU*job_walltime).
No idea. It CPU*Time is tracked though:
$ sreport user top Start=2015-07-21
Cluster Login Proper Name Account Used Energy
------- ----- --------------- --------------- ------------- --------
hpc user1 Bob Destruction mathgrp 17536898898 0
hpc user4 Steve Test physicsgrp 2432346047 0
hpc user3 Jane Entropy geogrp 142683133 0
hpc user2 Joe Random enggrp 52373384 0
So it a script could query the used field (CPU*time) and then set
GrpMEM/GRPCPU to zero and even kill jobs. There's probably a more
elegant way to do this though.
