We could get into an interesting discussion about the best way to decrease
the typical power use of a cluster. The best way to do this is with
software -- laptop-style power control, and powering nodes down. But when
purchasing and installing clusters you have to design for that
long-running job that stays at the peak power draw and thermal state of
the cluster.
Been waiting for <<weeks>> for a straight line.

and IBM's
forthcoming Blue Gene/P are about 3 watts per peak gigaflop.
I do agree though, that if you aren't computing anything, then you may as
well unplug the machine.
