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.
