Merlin contains a multi-cluster setup, where multiple Slurm clusters coexist under the same umbrella.
It basically contains the following clusters:
* The **Merlin6 Slurm CPU cluster**, which is called [**`merlin6`**](/merlin6/slurm-access.html#merlin6-cpu-cluster-access).
* The **Merlin6 Slurm GPU cluster**, which is called [**`gmerlin6`**](/merlin6/slurm-access.html#merlin6-gpu-cluster-access).
* The *old Merlin5 Slurm CPU cluster*, which is called [**`merlin5`**](/merlin6/slurm-access.html#merlin5-cpu-cluster-access), still supported in a best effort basis.

### Merlin6 GPU cluster access
The **Merlin6 GPU cluster** (**`gmerlin6`**) is visible from the login nodes. However, to submit jobs to this cluster, one needs to specify the option `--cluster=gmerlin6` when submitting a job or allocation.
