It sounds nice in >theory, but doesn't work as well. Apparently your power and cooling bills are much lower than ours. We would very much love it if the computers will use only the energy they need to get the job done. Yes, that means a big bill when some simulation is running on a 100-node beowulf cluster. But it also means we don't want to be paying the bill to run that cluster at full-throttle when there's no work for those CPU's to do. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
