+# Example of a job to start an executable in a Parallel environnement #
 
+## MPI ##
+Here is an example of a simple job to start an executable orchidee_ol (or gcm.e commented). 
+The input files and the executable must be in the directory before starting the executable.
+{{{
+#!/bin/bash
+#SBATCH --job-name=TravailMPI      # name of job
+#SBATCH --ntasks=80                # total number of MPI processes
+#SBATCH --ntasks-per-node=40       # number of MPI processes per node
+# /!\ Caution, "multithread" in Slurm vocabulary refers to hyperthreading.
+#SBATCH --hint=nomultithread       # 1 MPI process per physical core (no hyperthreading)
+#SBATCH --time=00:10:00            # maximum execution time requested (HH:MM:SS)
+#SBATCH --output=TravailMPI%j.out  # name of output file
+#SBATCH --error=TravailMPI%j.out   # name of error file (here, in common with output)

+# go into the submission directory
+cd ${SLURM_SUBMIT_DIR}
