In qmgr you have to do:

set server resources_available.nodect = 100

It's a kludge to make nodes be valid up to that number, and then Maui 
can use that as the number of CPU's that you want.

I still think Torque needs something like:

qsub -l cpus=100 pbs.sh

So it is unambiguous that you are asking for 100 CPUs..

The ncpus option is for SMP systems, and (IIRC) is really asking for
