[Moabusers] JOBNODEMATCHPOLICY

[Prakash Velayutham]

Hello All,

I am sure this question has been answered before, but I just can't  
seem to get the information out somehow.

I have Moab 5.1.0p8 and Torque 2.1.8.

In moab.cfg, I have NOT set JOBNODEMATCHPOLICY.

And these are all my requirements.

1) Ask for N procs in any fashion in the cluster

qsub -lnodes=N works just fine for this.

2) Ask for X nodes each with exactly N procs.

qsub -lnodes=X:ppn=N works fine for all N except for when N=1.
