[slurm-users] Limit Number of Jobs per User in Queue?

[Renfro, Michael]

In addition to Sean’s recommendation, your user might want to use job arrays [1]. That’s less stress on the scheduler, and throughput should be equivalent to independent jobs.

Howdy,

We are running Slurm 18.08. We have a user who has, twice, submitted over 15 thousand jobs to the cluster (the queue normally has a couple thousand jobs at any given time).

This results in Slurm being unresponsive to user requests / job submits. I suspect the scheduler is getting bogged down doing backfill processing.

Is there any way to limit the maximum number of jobs a single user can have in the queue at any given time?
