Prerequisites to connect to SCITAS clusters:


Our clusters

The clusters are accessible via SSH at the following adresses:


bellatrix.epfl.ch
castor.epfl.ch 
deneb1.epfl.ch 
deneb2.epfl.ch
fidis.epfl.ch

Step-by-step guide

  1. Log to a cluster using your GASPAR username and password as follows:

    ssh -Y <myusername>@<mypreferedcluster>.epfl.ch

    SSH clients

    SSH clients are available by default on MacOS X and Linux. For windows, we recommend PuTTY.

  2. Once logged in, you have access to your home directory at /home/<username>. 

    Your home directory is the same on all SCITAS clusters, and is limited by a quota of 100GB per user. Home files are backed up every night. This means that important files like source code, consolidated simulation results, etc should go here. 


  3. On each cluster, you have also access to a private scratch directory at /scratch/<username>.

    Scratch file systems are local to each cluster and are fast. This is typically where raw results, checkpoints, large temporary datasets will go. Scratch files are not backed up and files older than two weeks are subject to automatic deletion by a daily cleanup procedure.


Please note that from outside the EPFL network you will need to connect to the VPN
