About Merlin6 GPU cluster
Introduction
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 'gmerlin6'
THe GPU nodes have a dedicated Slurm cluster, called gmerli6.
This cluster contains the same shared storage resources (/data/user, /data/project, /shared-scracth, /afs, /psi/home)
which are present in the other Merlin Slurm clusters (merlin5,merlin6). The Slurm gmerlin6 cluster is maintainted
independently to ease access for the users and keep independent user accounting.
