mpitests-container

Provides a RockyLinux 8 container image with MPI libraries, Intel MPI Benchmarks (IMB) and OSU Micro Benchmarks (OMB), for use with with Singularity/Apptainer to provide MPI tests on clusters.

Currently the image it contains the following packages:

    git
    python3.9 
    mpitests-mpich
    mpitests-mvapich2
    mpitests-mvapich2-psm2
    mpitests-openmpi

Note the mpitests-* packages provide binaries for IMB, OMB and the relevant MPI library in a directory derived from the package name. For example for mpitests-openmpi the directory /usr/lib64/openmpi/bin/ contains the OpenMPI mpirun binary plus mpitests-IMB-MPI1, mpitests-osu_bw and others.

Example of running IMB-MPI1 pingpong using OpenMPI under Slurm using srun as the launcher:

#!/usr/bin/env bash
#SBATCH -N2
#SBATCH --ntasks-per-node=1
MPI_CONTAINER_TAG="main"
echo SLURM_JOB_NAME: $SLURM_JOB_NAME
echo $SLURM_JOB_ID: $SLURM_JOB_NODELIST
srun singularity exec docker://ghcr.io/stackhpc/mpitests-container:${MPI_CONTAINER_TAG} /usr/lib64/openmpi/bin/mpitests-IMB-MPI1 pingpong
