How to access the clusters
The DCSR maintains a general purpose cluster (Curnagl) which is described here. Researchers needing to process sensitive data must use the air gapped cluster Jura.
There are 3 requirements to be able to connect to Curnagl:
- To be part of a PI project
- To be on the UNIL network (either physically or using the UNIL VPN if you work remotely)
- 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: https://conference.unil.ch/research-resource-requests/. 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 the cluster
ssh -X <username>@curnagl.dcsr.unil.ch
<username> is your UNIL username name. You will have to enter your UNIL password.
Note: we strongly recommend you to establish SSH keys to connect to the clusters and to protect your SSH keys with a passphrase.
More details are available regarding the different clients in this documentation.
