Node and GPU Configuration

Compute Nodes and GPU Cards

Dirac is a 50 GPU node cluster connected with QDR IB.  Each GPU node also contains 2 Intel 5530 2.4 GHz, 8MB cache, 5.86GT/sec QPI Quad core Nehalem processors (8 cores per node) and 24GB DDR3-1066 Reg ECC memory.

  •  44 nodes:  1 NVIDIA Tesla C2050 (code named Fermi) GPU with 3GB of memory and 448 parallel CUDA processor cores. 
  • 4 nodes:  1 C1060 NVIDIA Tesla GPU with 4GB of memory and 240 parallel CUDA processor cores.
  • 1 node:  4 NVIDIA Tesla C2050 (Fermi) GPU's, each with 3GB of memory and 448 parallel CUDA processor cores.
  •  1 node:  4 C1060 Nvidia Tesla GPU's, each with 4GB of memory and 240 parallel CUDA processor cores.
  • 1 node: Tesla K20Xm
  • 1 node: Tesla K40c
