Hi,

Is there a mechanism for dynamically changing rqs' when the clusters
resources are below some overall usage threshold, in order to allow more
jobs to run?

I've got 300 cores, and sometimes only a few users are running anything
with lots of queued jobs. With a quota of 32 cores each, there are a lot of
unused cores. If the scheduler could recognize this and enough queued jobs
to fill maybe 75% of the cores, that'd be great.

If not a direct mechanism to do this, would a subordinate queue be best?
One that suspends running jobs when the main queue fills up? However, these
seems less ideal, since the suspended jobs might stay suspended for a long
time if the main queue fills up with a lot of jobs all of a sudden.
