## About Merlin6
|
|
|
|
Merlin6 is a the official PSI Local HPC cluster for development and
|
|
mission-critical applications that has been built in 2019. It replaces
|
|
the Merlin5 cluster.
|
|
|
|
Merlin6 is designed to be extensible, so is technically possible to add
|
|
more compute nodes and cluster storage without significant increase of
|
|
the costs of the manpower and the operations.
|
|
|
|
Merlin6 is mostly based on **CPU** resources, but also contains a small amount
|
|
of **GPU**-based resources which are mostly used by the BIO experiments.
|
|
|
|
### Slurm 'merlin6'
|
|
|
|
**CPU nodes** are configured in a **Slurm** cluster, called **`merlin6`**, and
|
|
this is the _**default Slurm cluster**_. Hence, by default, if no Slurm cluster is
|
|
specified (with the `--cluster` option), this will be the cluster to which the jobs
|
|
will be sent.
