I found this http://mvapich.cse.ohio-state.edu/performance/mvapich2/opteron/MVAPICH2-opteron-gen2-DDR.shtml as reference value for MPI-latency of Infiniband. I try to reproduce those numbers at the moment but i'm stuck with # OSU MPI Latency Test v3.0 # Size Latency (us) 0 3.07 1 3.17 2 3.16 4 3.15 8 3.19 Equipment is two quadsocket Opteron Blades (Supermicro) with Mellanox Ex DDR cards. Single 24 port switch connects them. Can anybody help with suggestions what i can do to lower the latency?
Regards, Jan |
Bye Jan
