Instructions for running IMB pingpong.

  1. Add the following to openhpc_packages:
  • lmod-defaults-gnu9-openmpi4-ohpc
  • imb-gnu9-openmpi4-ohpc

Note the former automatically loads gnu9+openmpi4 on login - if you don't use this add "module load gn9 openmpi4" to the sbatch script below.

  1. Use an sbatch script like this:
#!/bin/bash
#SBATCH --ntasks=2
#SBATCH --ntasks-per-node=1
#SBATCH --output=%x.out
#SBATCH --error=%x.err
#SBATCH --time=0:10:0
#SBATCH --exclusive
export SLURM_MPI_TYPE=pmix_v3
module load imb
srun IMB-MPI1 pingpong
