Performance Impact to NAS LU for Checkpointing

  • Experimental Testbed: Dual Intel PCI-Express cluster equipped with Mellanox MHGA28-1TC (DDR) HCA. MVAPICH2 running on OpenFabrics OFED 1.1 stack. The storage system is PVFS2(version 1.5.1) with 8 servers, the network for PVFS2 is IPoIB
  • Checkpoints only incur small performance impact to LU.
