We run a reasonable size Condor Pool: ~ 2500 processor cores at the
moment, based on student teaching clusters around the campus. We are
experimenting with wake-on-LAN, as supported by Condor. There are some
issues, for example, our Network Unit don't like WOL packets flying around
between buildings.

I believe that some UK universities:
- don't turn PCs on for Condor use (but only use ones that are already
on); or
- are running Condor (or similar HTC) on "big iron" rather than PC

I would welcome comments on how _you_ are reacting to the Green agenda.
