[slurm-users] Areas for improvement on our site's cluster scheduling

We've been using a backfill priority partition for people doing HTC 
work.  We have requeue set so that jobs from the high priority 
partitions can take over.

You can do this for your interactive nodes as well if you want. We 
dedicate hardware to interactive work and use Partition based QoS's to 
limit usage.

I’ve just added a root-only ‘expedited’ QOS for times when the cluster is mostly idle, but a few users have jobs that run past the TRES limit. But I really like the idea of a preemptable QOS that the users can put their extra jobs into on their own.
