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
