Chris (and all who've responded),
Thank you for the responses. It's given me some directions to explore.
At present, I have just the default queue on one cluster, and two queues -
one for the machines with GPUs, and one for machines without GPUs - on the
The "fairshare-by-user" policy sounds very interesting; users typically
only complain when one user is monopolizing the cluster, submitting
hundreds of jobs, forcing anyone else to join the end of the line with
