The Space Simulator is a 294-processor [URL=http://www.beowulf.org/]Beowulf[/URL] cluster. It is based on the [URL=http://www.shuttleonline.com/specs2.asp?pro_id=76] Shuttle XPC SS51G[/URL] mini chassis, which uses a heat pipe instead of a CPU fan. The small size of the XPC cases allowed us to fit the cluster in about half the space of the previous 144-processor [URL=http://cnls.lanl.gov/avalon]Avalon[/URL] cluster.

I want one ;) Go [URL=http://space-simulator.lanl.gov/]here[/URL] to see a photo of the supercomputer, makes a nice wallpaper...
