Requires:
OSU Micro-Benchmarks 5.3.2 (09/09/16)
http://mvapich.cse.ohio-state.edu/benchmarks/
Build:
- tar xzf osu-micro-benchmarks-5.3.2.tar.gz
- cd osu-micro-benchmarks-5.3.2/mpi
- patch -p1 < ~/osu.pt2pt.patch
- build OSU and link osu_latency with caflu files
Test bed:
- CPU: dual-socket Intel Xeon E5-2650 v3; HT active; governor: powersave
- NIC: Mellanox FDR ConnectX-3 VPI adapter; in IB mode; with IPoIB enabled
- Switch: Mellanox SX6036
- Topology: 2 nodes plus 1 IB switch with static MinHop routing
- OS: CentOS Linux release 7.3.1611
- MPI: Intel(R) MPI Library 2017 Update 1
- Compiler: gcc version 4.8.5 20150623
- OFED: MLNX_OFED_LINUX-3.4-2.0.0.0
Run without and with cache flushes (requ. changes in .c file and recompilation):
- exclusive access to nodes and network during tests
- mpirun -n 2 -ppn 1 -env I_MPI_FABRICS tcp -hosts h1,h2 ./osu_latency -x 4 -i 128
