[slurm-users] Partition question

[Ransom, Geoffrey M.]

Hello
   I am looking into switching from Univa (sge) to slurm and am figuring out how to implement some of our usage policy in slurm.

We have a Univa queue which uses job classes and RQSes to limit jobs with a run time over 4 hours to only half the available slots (CPU cores) so some slots are always free for quick jobs. We don't want all of our resources tied up with multiweek jobs when someone has a batch of 1 hour jobs to run.

Is there a way to implement this in slurm? To have a partition which will hold some CPU/GPU resources aside for jobs with a short runtime.

What would be the preferred solution for this issue in a slurm world?
