The ISU cluster consists of 48 HP workstations, model xw9300. Each has two AMD Opteron processors, and two nVIDIA Quadro FX 4500 GPUs (not configured in SLI mode). There's a bunch of nVIDIA G-sync connectivity to lock the video frames and buffer swaps. The workstations are running Linux.
Undisclaimer: I work for HP. :-)
