This script is just spawning jobs on the nodes that are using less cpu
time, right?   If you are using our latest release, -8, mpich
automatically uses beomap to map which nodes the jobs go to, and
beomap's default behavior is to automatically map the jobs to the nodes
that have the lowest cpu usage.

Is there something to this script that I'm missing that mpich with
beomap doesn't do for you?
