Remind me again how many machines on this network? And did your measurements include monitors or only processors? ..... as measured on the public utility meter---- for *twelve* systems, router, access points(2), printers (3), flat panels(4) and ThinkPad (plugged in). So, to put this in perspective, my 12 cup Krups coffee maker consumes 820 watts... Yes, all of this was at one time on one circuit. Its spread all over the house now. Most of our systems are run headless. However, during my measurements the (4) flat panels were powered up and lit.
The main points here were basically these: 1) A nice home cluster can be cheaply constructed from old pc hardware running Suse linux. Don't throw those old boxes out just because Windoze X-tra Pricy won't run on them... ;-) 2) Home clusters can be operated cheaply... and now I know how cheaply... for less bucks than running your basic drip coffee maker.... -- Kind regards, M Harris <><
