Performance numbers of MVAPICH2 on Sandy Bridge Architecture (05/06/13)

  • Experimental Testbed: Each node of our testbed has two 8-core 2.6 GHz Intel Xeon E5-2670 (Sandy Bridge) processors and 32 GB main memory. The nodes support 16x PCI Express Gen3 interfaces and are equipped with Mellanox ConnectX-3 EN adapters. The operating system used was RedHat Enterprise Linux Server release 5.4 (Tikanga). The processes were bound to core 1 on both nodes
  • MVAPICH2 currently delivers one-sided put latency of 1.85 microseconds for 4 bytes, one-sided get latency of 3.50 microseconds for 4 bytes, one-sided put bandwidth up to 4549.47 Million Bytes/sec, one-sided get bandwidth up to 4546.69 Million Bytes/sec and put bidirectional bandwidth upto 9041.22 Million Bytes/sec on the above testbed. (1 Mega Byte = 1,048,576 Bytes; 1 Million Byte = 1,000,000 Bytes)
