Performance Impact to NAS (LU and SP) for Checkpointing

  • Experimental Testbed: 16 Intel Xeon servers having 8 cores and Mellanox MT25208 InfiniBand DDR Adapter, running RHEL 5.2. MVAPICH2 running on OpenFabrics OFED 1.3 stack. The storage system is Lustre with 4 servers running native InfiniBand.
  • Checkpoints only incur very small performance impact to NAS (LU and SP).
