Getting Access

GWDG Account and HPC Project

You need two things before connecting:

  • A GWDG account (available to all Uni Göttingen members)
  • Membership in our group's HPC project — email Sebastian Hanß to be added. You will receive a separate HPC username (e.g. u12345) used for all HPC work.

SSH Key

Generate an SSH key pair on your local machine:

ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519

Log into your GWDG account settings, go to Security → Add SSh public keys, and paste the contents of ~/.ssh/id_ed25519.pub there.

SSH Config

Add the following to ~/.ssh/config, replacing u12345 with your HPC username:

Host Emmy-p3
    Hostname glogin-p3.hpc.gwdg.de
    User u12345
    IdentityFile ~/.ssh/id_ed25519

You can then connect with:

ssh Emmy-p3

Emmy-p3 is reachable from outside the university network without VPN.

Open Questions

  • Does GWDG account activation require a separate email to hpc-support@gwdg.de, or is adding someone to the project via the portal sufficient?
  • Should the SSH key also be registered separately in the HPC project portal, or does the GWDG account registration cover it?
