If you name you parallel environment something besides ORTE, it won't
get blown away when new nodes are added/removed. I usually create one
called "amp" and I change the slots for that PE to be "999". It will
then fill the nodes up with jobs up to each individual nodes number of
slots (cpus). I'm sure this could be done as a plugin, but it isn't
there now as far as I'm aware. My cluster is long running, so to date
we've just updated the qconf when we launch a new cluster.
