## 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.
|
|
|
