[slurm-dev] poor utilization, jobs not being scheduled

[Vlad Firoiu]

I'm trying to figure out why utilization is low on our university cluster.
It appears that many cores are available, but a minimal resource 10 minute
job has been waiting in queue for days. There happen to be some big high
priority jobs at the front of the queue, and I've noticed that these are
being constantly scheduled and unscheduled. Is this expected behavior?
Might it be causing slurm to never reach lower priority jobs and consider
them for scheduling/backfill?
