+## 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.
