[torqueusers] Using procs and grouping by even numbers of processors/node

Hello All-

Another question that has come up in the use of the procs qsub argument. When you run GAMESS, apparently you need to group the processors evenly among nodes. In other words, if you ask for procs=4 and 3 processors are allocated on one node and 1 allocated on the other, the job will fail since GAMESS requires that an even number of processes be available on the nodes on which it runs. In this case, the job would have been successful if 2 processes were started on one node and 2 processes were started on the other. Is there anyway to modify or augment the procs option in order to make sure that an even number of processes are started on each node?

Thanks!

-Lance
