The DAVinCI system is an IBM iDataPlex consisting of 2304 processor cores in 192 Westmere nodes (12 processor cores per node) at 2.83 GHz with 48 GB of RAM per node (4 GB per core).  All of the nodes are connected via QDR InfiniBand (40 Gb/s ) both to each other and to the GPFS fast scratch storage system.  Sixteen (16) of the nodes are equipped with NVIDIA Fermi GPGPUs.  This system is a hybrid system in that it incorporates HTC (high throughput computing) or “serial” jobs and tightly-coupled “parallel” (MPI) jobs along with General-Purpose Computing on Graphics Processing Units (GPGPU) and 3D stereo visualization.
