Others have powered multiple motherboards from a single power supply, so it probably can be made to work with your hardware too, but the only way to know for sure is to try it. I myself did some initial experimentation along those lines, but I never got around to actually installing and using Linux on the nodes in that configuration: http://www.scyld.com/pipermail/beowulf/2004-September/010766.html http://www.scyld.com/pipermail/beowulf/2004-October/010974.html http://www.scyld.com/pipermail/beowulf/2004-October/010981.html This cluster used multiple nodes per power supply: http://www.abo.fi/~physcomp/cluster/celeron.html http://physics.bu.edu/~sandvik/clusters.html These clusters did not, but are also "box of bare boards" designs, so might be relevent to you: http://jessen.ch/ammonite/ http://www.phys.utb.edu/beowulf/ http://krone.physik.unizh.ch/~stadel/zBox/story.html http://krone.physik.unizh.ch/~stadel/zBox/ http://mini-itx.com/projects/cluster/ > This is a power-saving concept... if I could run 16 mobo's on 8 (or even 6) > power supplies, it might be more beneficial to my health and well-being when > the electric bill comes in. Might be, I guess, especially if those power supplies were more efficient models. Since this is a home hobbyist cluster however, you're likely to save a lot more by automatically turning the nodes off whenever you're not actually using them, and then booting them up fast with Wake-on-LAN and PXE - if they support that. -- Andrew Piskorski <[EMAIL PROTECTED]> http://www.piskorski.com/ _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
