unfortunately, we haven't been able to run the inferno grid stuff on
any more than about 300 nodes. it works fairly quickly on that
number, but task takeup slows down considerably when it's pumping out
a lot of data (this is better now that nodes cache data).
things are slowed down quite a bit by logging constraints (it stores
much on-going data on disk, both to reduce memory consumption and so
that if the server crashes or is turned off, things can resume with
virtually nothing lost). running on top of a ram disk can speed
things up by at least an order of magnitude. this probably makes
sense for short-lived jobs.
i'd love to try it out on a larger cluster (one could use an existing
scheduler to leverage the initial installation).
