This is the old chestnut that there is no simple way to request an allocation 
of N cpus anywhere in the cluster through Torque.  I'd suggested a possible 
option of:

 -l cpus=N 

but that would require changes in pbs_sched, Maui and Moab to support it.

The kludge around this is to set, through qmgr:

 set server resources_available.nodect = N

where N is the total number of CPUs in the cluster.
