How to access the clusters

The DCSR maintains several clusters (Wally, Axiom and Jura) which are described here. There are 3 requirements to be able to connect to the clusters:

  1. To be part of a PI project
  2. To be on the Unil network (either physically or using the Unil VPN if you work remotely)
  3. To have a ssh client

Step 1: Be part of a PI project

To access the clusters, your PI will first need to request resources via: Then the PI must add you as a member of one of his project. Within 24 hours your access should be granted.

Step 2: Activate the Unil VPN

Unless you are physically within the Unil network you need to activate the Unil VPN (Crypto). Documentation to install and run it can be found here.

Step 3: Open a ssh client

On Linux and Mac environments, a ssh client should be available by default. You simply need to open a terminal.

Windows users can either use PowerShell if they are on Windows 10, or install a third party client such as PuTTy or MobaXterm.

Step 4: Log into a cluster

Cluster Login command
Wally ssh -X <username>
Axiom ssh -X <username>

where <username> is your UNIL username name. You will have to enter your UNIL password.
