The Accelerator Research Cluster (ARC) is a technology evaluation cluster with a combination of 14 IBM PowerXCell 8i "Cell" nodes and 8 Intel x86_64 "Nehalem" nodes containing 16 NVIDIA M2070 GPUs. The QS22's each have two 3.2GHz "IBM PowerXCell 8i CPU's, where each CPU has 1 Power Processing Unit (PPU) and 8 Synergistic Processing Units (SPU), and 32GB of RAM per node. The Intel nodes have two 2.53GHz 4core Xeon X5550 CPU's with 48GB of RAM per node each containing two NVIDIA M2070 (Fermi) GPU's each with 6GB of RAM.

Please note that this cluster is not a production cluster and is only accessible to selected users.
