No.  The patch doesn't address scheduling at all.  It's up to mpirun
to chose nodes and place the right number of jobs on each node.
mpirun can use anything at all to make those decisions.

The mpirun I wrote (which I will probably get out some time after
xmas) doesn't do any resource allocation at all.  We were hoping to
trick somebody err... I mean encourage somebody to write an open
scheduler for a system like this.  We'll probably try to allocate a
student to that probalem some time in the future.

Nope.  Use whatever you want.
