Gareth, have you gotten this to scale? I've also been looking for a way to
trick HP-MPI (now Platform MPI) into using the PBS TM, but I have not been
able to get pbsdsh to scale beyond a couple of hundred nodes. The Mother
Superior basically starts taking up 100% of a core and stops responding.
I'd like to be able to get it up to at least 1024 pbsdsh calls, and it
doesn't get even close.
