Merlin contains a multi-cluster setup, where multiple Slurm clusters coexist under the same umbrella.
It basically contains the following clusters:
* The **Merlin7 Slurm CPU cluster**, which is called [**`merlin7`**](/merlin7/slurm-access.html#merlin7-cpu-cluster-access).
* The **Merlin7 Slurm GPU cluster**, which is called [**`gmerlin7`**](/merlin7/slurm-access.html#merlin7-gpu-cluster-access).
* The **Merlin7 Slurm CPU cluster**, which is called [**`merlin7`**](#merlin7-cpu-cluster-access).

The **Merlin7 CPU cluster** (**`merlin7`**) is the default cluster configured in the login nodes. Any job submission will use by default this cluster, unless
the option `--cluster` is specified with another of the existing clusters.
For further information about how to use this cluster, please visit: [**Merlin7 CPU Slurm Cluster documentation**](/merlin7/slurm-configuration.html#cpu-cluster-merlin7).

### Merlin7 GPU cluster access
The **Merlin7 GPU cluster** (**`gmerlin7`**) is visible from the login nodes. However, to submit jobs to this cluster, one needs to specify the option `--cluster=gmerlin7` when submitting a job or allocation.
For further information about how to use this cluster, please visit: [**Merlin7 GPU Slurm Cluster documentation**](/merlin7/slurm-configuration.html#gpu-cluster-gmerlin7).

* It is **forbidden** to use the ``/data/user`` or ``/data/project`` for that purpose.
* Always remove files you do not need any more (e.g. core dumps, temporary files) as early as possible. Keep the disk space clean on all nodes.
* Prefer ``/scratch`` over ``/data/scratch/shared`` and _use the latter only when you require the temporary files to be visible from multiple nodes_.

## User and project data
* ***Users are responsible for backing up their own data***. Is recommended to backup the data on third party independent systems (i.e. LTS, Archive, AFS, SwitchDrive, Windows Shares, etc.).
* ***When a user leaves PSI, she or her supervisor/team are responsible to backup and move the data out from the cluster***: every few months, the storage space will be recycled for those old users who do not have an existing and valid PSI account.
