Technical Overview

Microbenchmarks suite to evaluate MPI and PGAS (OpenSHMEM, UPC, and UPC++) libraries for CPUs and GPUs.

The following MPI, OpenSHMEM, UPC and UPC++ tests are included in the OMB package:

Point-to-Point MPI Benchmarks: Latency, multi-threaded latency, multi-pair latency, multiple bandwidth / message rate test bandwidth, bidirectional bandwidth
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).
Point-to-Point OpenSHMEM Benchmarks: put latency, get latency, message rate, atomics,
Collective OpenSHMEM Benchmarks: collect latency, broadcast latency, reduce latency, and barrier latency
Point-to-Point UPC Benchmarks: put latency, get latency
Collective UPC Benchmarks: broadcast latency, scatter latency, gather latency, all_gather latency, and exchange latency
Point-to-Point UPC++ Benchmarks: async copy put latency, async copy get latency
Collective UPC++ Benchmarks: broadcast latency, scatter latency, gather latency, reduce latency, all_gather latency, and all_to_all latency
Startup Benchmarks: osu_init, osu_hello

Relationship to component?

[ X] contributing developer
[ ] user
[ ] other

If other, please describe:

Build system

[ X] autotools-based
[ ] CMake
[ ] other

If other, please describe:

Does the current build system support staged path installations? For example: make install DESTIR=/tmp/foo (or equivalent)

[X ] yes
[ ] no

The OSU Micro-Benchmarks use the GNU build system. Therefore you can simply use the following steps to build the MPI benchmarks.

Example: ./configure CC=/path/to/mpicc CXX=/path/to/mpicxx make make install

Does component run in user space or are administrative credentials required?

[ X] user space
[ ] admin

Does component require post-installation configuration.

[ ] yes
[X ] no

If yes, please describe briefly:

If component is selected, are you willing and able to collaborate with OpenHPC maintainers during the integration process?

[ X] yes
[ ] no

Does the component include test collateral (e.g. regression/verification tests) in the publicly shipped source?

[ ] yes
[X ] no

If yes, please briefly describe the intent and location of the tests.

Does the component have additional software dependencies (beyond compilers/MPI) that are not part of standard Linux distributions?

[X ] yes
[ ] no

If yes, please list the dependencies and associated licenses.

OSU Microbenchmarks have support for transferring data from/to host to/from GPUs. If using this feature, OMB would require CUDA to be installed on the system.

Does the component include online or installable documentation?

[X ] yes
[ ] no

If available online, please provide URL. http://mvapich.cse.ohio-state.edu/static/media/mvapich/README-OMB.txt

[Optional]: Would you like to receive additional review feedback by email?

- [ X] yes - [ ] no
