+==== Using a shared node ====
+If your case isn't that demanding on hardware and you are interested in a fast solution, it is possible to use one of the shared nodes. These are non-exclusive nodes, thus more than just one job is able to use the provided hardware.
+On these nodes you have to tell SLURM, how much memory (RAM) your case would need. This value should be less than the maximum of 96GB these nodes uses. Otherwise your job needs a whole node anyway.
+Here we use --mem=20G, to dedicate 20GB of memory.
+<code>
+#!/bin/bash
+# slurmsubmit.sh
+#SBATCH -n 1
+#SBATCH --ntasks-per-node=1
+#SBATCH --job-name="clustsw"
+#SBATCH --qos=mem_0096
+#SBATCH --mem=20G
+hostname
+module purge
+module load Comsol/5.6
