[torquedev] Torque ncpus command

[Lenox, Billy AMRDEC/Sentient Corp.]

Here /var/spool/torque/server_priv/nodes

seed001 np=8 batch
seed002 np=8 batch
seed003 np=4 batch
seed004 np=4 batch
seed005 np=4 batch

Scheduler = PBS

Correct the -l procs=28 does not work over all Nodes Only the First One
(seed001)
