Our cluster has ~2,600 cores, there are parallel jobs running to fill ~1,700
and there are many sequential jobs queue that are now in "front" of other 
parallel jobs. But only one or two of the sequential jobs are running, the 
others being held by the user.

The parallel jobs are not schedulled. The scheduler is maui. Any idea what I 
am missing here?
