The other thing to look at is the job_load_adjustments in the scheduler 
config.  If it's set to 0:0:0, the scheduler will fill up machines 
instead of distributing the load.

Multiple jobs are being submitted to same node, while the other nodes are idling, instead it would be nice to submit one job to each available free node and submit another if none available.
