Compute nodes

Compute Node Configuration

    • 5,576 nodes
    • two 12-core Intel "Ivy Bridge" processors at 2.4GHz per node
    • 24 cores per node (133,824 total cores)
    • 1 AVX (vector) functional group
      • 256 bits wide
      • 1 add and a multiply
    • Peak Gflop/s rate:
      • 19.2 Gflops/core
      • 460.8 Gflops/node
      • 2.57 Peta-flops for the entire machine
    • 64 GB DDR3 1600 MHz memory per node (four 8 GB DIMMs per socket)
    • Each core has its own L1 and L2 caches, with 64 KB and 256 KB, respectively
    • One 30-MB L3 cache shared between 12 cores on the "Ivy Bridge" processor
    • Cache BW per core
      • L1/L2/L3 = 100/40/23 Gbytes/s
    • Stream TRIAD BW /Node = 89 Gbytes/s
    • Memory latency = 82 ns
