I don't know the answer to the following question, but does that comparison take into account cooling costs? Particularly as one loads up a building with many computers, you realize you are also buying air conditioners to cool things back down. Just wondering.. I'm not pretending that better HLT use will save the planet, but it's definitely true that my office is warmer when I have some background process soaking up idle cycles than if I leave things idle. It's also true that RPI's cooling of the computer center has a few problems, particularly in the early spring and late fall. (when it's "too cool" to turn on the "big chillers", but still too warm for the number of computers we have in our offices). -- --- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
