%global desc OSU Micro-Benchmarks for MPI.\
Point-to-Point MPI Benchmarks: Latency, multi-threaded latency, multi-pair\
latency, multiple bandwidth / message rate test, bandwidth, bidirectional\
bandwidth\
Blocking Collective MPI Benchmarks: Collective latency tests for various MPI\
collective operations such as MPI_Allgather, MPI_Alltoall, MPI_Allreduce,\
MPI_Barrier, MPI_Bcast, MPI_Gather, MPI_Reduce, MPI_Reduce_Scatter, MPI_Scatter\
and vector collectives.\
Non-Blocking Collective (NBC) MPI Benchmarks: Collective latency and Overlap\
tests for various MPI collective operations such as MPI_Iallgather,\
MPI_Iallreduce, MPI_Ialltoall, MPI_Ibarrier, MPI_Ibcast, MPI_Igather,\
MPI_Ireduce, MPI_Iscatter and vector collectives.\
One-sided MPI Benchmarks: one-sided put latency, one-sided put bandwidth,\
one-sided put bidirectional bandwidth, one-sided get latency, one-sided get\
bandwidth, one-sided accumulate latency, compare and swap latency, fetch and\
operate and get_accumulate latency for MVAPICH2 (MPI-2 and MPI-3).\
Startup Benchmarks: osu_init, osu_hello
