# Accessing Slurm Cluster
|
|
|
|
## The Merlin Slurm clusters
|
|
|
|
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-cpu-cluster-access).
|
|
* The **Merlin7 Slurm GPU cluster**, which is called [**`gmerlin7`**](#merlin7-gpu-cluster-access).
|
|
|
|
## Accessing the Slurm clusters
|
|
|
|
Any job submission must be performed from a **Merlin login node**. Please refer to the [**Accessing the Interactive Nodes documentation**](accessing-interactive-nodes.md)
|
|
for further information about how to access the cluster.
|
|
|
|
In addition, any job *must be submitted from a high performance storage area visible by the login nodes and by the computing nodes*. For this, the possible storage areas are the following:
|
|
* `/data/user`
|
|
* `/data/project`
|
|
* `/data/scratch/shared`
|
|
|
|
### 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**](../03-Slurm-General-Documentation/slurm-configuration.md#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**](../03-Slurm-General-Documentation/slurm-configuration.md#gpu-cluster-gmerlin7).
