It may also be useful to see what the checkjob command says on the jobs that are not running.

Also, you will want to look at your torque config. It is possible there are limits at the torque level.

The issue is that the cluster will only run about 90 of them at a time with 85 out of the 344 processors active and only 12 of the nodes being used.  The jobs are all going to the default queue and there are no node or cpu/memory parameters added to the submissions.
