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. - The Merlin7 Slurm GPU cluster, which is called
gmerlin7.
Accessing the Slurm clusters
Any job submission must be performed from a Merlin login node. Please refer to the Accessing the Interactive Nodes documentation 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.
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.
