>Anyone exploring high FLOPS/watt clusters yet? We currently have a 768 node cluster RLX cluster in production. We were low on power capacity and physical space in our machine room so it made sense to pay the premium for the high density. When we did our evaluation we ended up with a test metric of BLASTs/Watt/Pound. 24 blades (800Mhz PIII, 2x40Gig drive, 3x100Mb ethernet per blade) fit into 3U and consume ~840 watts. Compaq/HP, IBM and Fujitsu also offer high density/low power blade solutions as well with various GigE/myrinet networking options should you require them. What solution you end up with depends on how much extra you want to spend on hardware in order to save on space and power.
