I ran into this a few months ago, and it had almost nothing to do with PE slots. Unfortunately, I can't recall what I did to fix it either. Try submitting test jobs with "-w v" and "-w p" to get more of an idea of what's going on.

Dear All, There are 144 nodes in my queue and I configured 1 slot for each node. That is 144 nodes with 144 slots. The PE is used 121 slots now. One job need 12 PE's slots and there are enough nodes and slots for this job. But it queued by "cannot run in PE "mpich" because it only offers 0 slots".
