First, the resources need to be requested via `salloc`:

```
salloc --nodes=1 --ntasks-per-node=96 --ntasks-per-core=1 --ntasks=96 --mem=500G --job-name=MPI-test --time=05:00:00 --partition=general --account=AccountString

```
Resources should be modified to be appropriate for your job as the example is asking for a full node on Bunya. It is important to keep `--ntasks-per-core=1`.
Only ever change this if you know exactly what you are doing and how to combine MPI with OpenMP.
