+## Understanding the Slurm configuration (for advanced users)
+
+Clusters at PSI use the [Slurm Workload Manager](http://slurm.schedmd.com/) as the batch system technology for managing and scheduling jobs.
+Historically, *Merlin4* and *Merlin5* also used Slurm. In the same way, **Merlin6** has been also configured with this batch system.
+
+Slurm has been installed in a **multi-clustered** configuration, allowing to integrate multiple clusters in the same batch system.
+
+For understanding the Slurm configuration setup in the cluster, sometimes may be useful to check the following files:
+
+* ``/etc/slurm/slurm.conf`` - can be found in the login nodes and computing nodes.
+* ``/etc/slurm/gres.conf`` - can be found in the GPU nodes, is also propgated to login nodes and computing nodes for user read access.
+* ``/etc/slurm/cgroup.conf`` - can be found in the computing nodes, is also propagated to login nodes for user read access.
+
+The previous configuration files which can be found in the login nodes, correspond exclusively to the **merlin6** cluster configuration files.
+Configuration files for the old **merlin5** cluster must be checked directly on any of the **merlin5** computing nodes: these are not propagated
+to the **merlin6** login nodes.
