New users

Prerequisites

  • A valid ETH account
  • Local computer with an SSH client
  • An X11 server for graphical user interface (optional)

How to get access

  • Request authorization of your ETH account from cluster-support@id.ethz.ch
  • 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
  • Accept the cluster’s usage rules upon the first login
  • Generate SSH keys for passwordless login by following the instruction here

Current users

To regain the access after the incident on 15 May 2020, all users have to change their LDAP password and generate new SSH keys.

  • Change your ETH password at https://password.ethz.ch
  • Wait for one working day. The change should become active on the next day from 8am
  • If you could still not access the cluster after one working day, please contact us.
  • Regenerate new SSH keys by following the instruction here

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 must create an ETH guest account for them, including e-mail address and VPN service
  • Once this is done, they can access Euler like members of ETH
