2.1. Purpose

The OSU Microbenchmarks (OMB) are widely used to measure and evaluate the performance of MPI operations for point-to-oiint, multi-pair, collective, and one-sided communications.

2.2. Characteristics

Official site: OSUMB

2.2.1. Problem

The OSU benchmarks are a suite of microbenchmarks designed to measure network characteristics on HPC systems.

2.3. Source code modifications

Please see Run Rules Synopsis for general guidance on allowed modifications.

2.4. Building

On GPU enabled systems add these flags to the following configure lines:

--enable-cuda
--with-cuda-include=/path/to/cuda/include
--with-cuda-libpath=/path/to/cuda/lib

Build and install the benchmarks.

./configure --prefix=$INSTALL_DIR
make -j
make -j install

Before configuring make sure your CXX and CC environment variables are set to an MPI compiler or wrapper. On most systems this will look like:

export CC=mpicc CXX=mpicxx

On systems with vendor provided wrappers it may look different. For example, on HPE-Cray systems:

export CC=cc CXX=CC

2.5. Running

For any GPU enabled system, please also include the GPU variants of the following benchmarks.
