But why run an older OS release? Something like CentOS-5.latest will run fine on your new hardware and it's no problem getting all sorts of old HPC code to run on it (disclaimer: of course you can find a zillion apps that break on any given OS...). > I was wondering if anyone has actual experience with running more than one > node from a single power supply. ... > Look at the Supermicro twin systems, they have two motherboards in 1U or > four motherboards in 2U. > > I believe HP have similar. They have 4-nodes in 2U (it has the added benefint of using large 8cm fans instead of those inefficient 1U fans...).
