Prototype MPI Workload

MPI-Workload: Sample MPI Workload

This is a sample MPI workload that can be used to test the MPI cluster or emulate a real workload.

Building

The project uses CMake to generate the build files. The following commands can be used to build the project:

# requires CMake 3.20 or newer

cd mpi-workload

# create a build directory and generate the build files
cmake -B build

# build the project
cmake --build build

# install the project
cmake --install build --prefix <install_dir>

Usage

cd build 

# supported options
./mpi-workload --help
# >output
Synthetic MPI Workload / Benchmark
Usage:
  mpi_workload [OPTION...]

  -h, --help          Print help
  -t, --threads arg   Number of threads to spawn on each rank (default: 1)
  -b, --buffer arg    Buffer size in KBs (default: 1)
  -d, --duration arg  Test duration in seconds (default: 10)

Currently only MPI_Alltoall based workload is supported. This may be extended in the future as needed.
