Scyld

[Todd Henderson]

I once built a script for a cluster of workstations where I never new if people would be on them or not that went
out and checked a couple of things, if anyone was physically on it, and if certain programs were running and then
built a list of free machines.  Seems like with some of the tools with scyld, it wouldn't be that hard to see
what machines were being used and which were and script it up to build a p4pg file.  You could create a wrapper
for mpirun or something?  Just a thought.
