Vincent, what makes you think that motherboard has Infiniband? Do you see connectors for it in the pictures or something? Arima's older SW500 quad socket 940 Opteron motherboard came in four versions, two of which had Infiniband (Mellanox MT25208). Thus, it's quite possible that this newer quad socket F board also had an Infiniband option, but I have no idea if this particular board has it or not. http://www.flextronics.com/computing/support/server/Product/ViewProduct.asp?View=SW500 > The problem is no manufacturer lists these boards and which PSU fits > on it and what cpu's is unclear. It's an Arima model 40GCMG020-D400-100. Perhaps it was intended as an OEM motherboard for Gateway or Dell; at least, I can't think of any other good reason why there's essentially no information whatsoever about it on web. Arima sold its computer business to Flextronics in 2007, perhaps that's related somehow. Chris Morrell (aka, "[XC] gomeler", a Georgia Tech student and sysadmin) seems to have made good progress in figuring out the functions of most of the pins on the motherboard's non-standard power connectors, but hasn't yet succeeded in getting his to boot: http://www.xtremesystems.org/forums/showpost.php?p=4194423&postcount=137 http://www.xtremesystems.org/forums/showpost.php?p=4224859&postcount=175 http://atrejus.net/arima/arima-gr.jpg http://forums.2cpu.com/showthread.php?s=e603598f0c265e1e0725a0b10b1a3757&p=772296#post772296 -- Andrew Piskorski <a...@piskorski.com> http://www.piskorski.com/ _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
