 ## Script explanation
 We are now describing the Slurm script [run.slurm](https://gitlab.oca.eu/DSI/HPC/-/blob/master/SLURM/MPI/build.sh). Note that we will run 2 task per node to illustrate the fact that the job will use more than one node, although this toy example would be happy with one job per core.

 ```
+#!/bin/bash
+#SBATCH --job-name=Dice            # job name
+#SBATCH --ntasks=4                 # Total number of MPI processes, could be deduced
+#SBATCH --ntasks-per-node=2        # Total number of MPI processes per node
+#SBATCH --time=00:10:00            # Maximum compute time (HH:MM:SS)
+#SBATCH --output=log-dice-%j.out  # Ouput file (%j is the job's id)
+#SBATCH --error=log-dice-%j.err   # Error file
+ 
+# Go to the submit dir
+cd ${SLURM_SUBMIT_DIR}
+ 
+# Cleanup the environment that could be inherited
+module purge
+
+# Load the needed modules, depends on your application
+module load intel-gnu8-runtime/19.1.2.254
+module load intelpython3 impi
+module load boost
+
+# Be verbose
+set -x
+
+# Run the code, one could also use mpiexec or mpirun
+srun --mpi=pmi2 ./dice
