Request an account on the clusters

Prerequisites

How to get access

  • Start your SSH client
  • Use ssh command to connect to the login node of Euler or Leonhard Open
 ssh username@euler.ethz.ch
 ssh username@login.leonhard.ethz.ch
  • Use your ETH credentials to login
  • Upon the first login, a verification code should be sent to your ETH email address (username@ethz.ch)
  • Enter the verification code to the prompt
An access code has been sent to your ETH email address.
Enter the access code at the prompt below.
If you do not receive the access code within a few minutes,
then contact us by opening a ticket at
http://smartdesk.ethz.ch

External collaborators

Members of other institutions who have a collaboration with a research group at ETH may use the clusters for the purpose of said collaboration

  • Their counterpart (“sponsor”) at ETH can create an ETH guest account, e-mail address and VPN service for them
  • Then, they can access Euler like members of ETH

Legal compliance

The HPC clusters are subject to ETH’s acceptable use policy for IT resources (Benutzungsordnung für Telematik (BOT)), in particular:

  • Cluster accounts are strictly personal
  • DO NOT share your account (password, sshkeys) with anyone
  • DO NOT use someone else’s account, even if they say it’s OK
  • If you suspect that someone used your account, change your password and contact cluster-support@id.ethz.ch

Consequences:

  • In case of abuse, the offender’s account may be blocked temporarily or closed
  • System administrators are obliged by law to investigate abusive or illegal activities and report them to the relevant authorities
