How to log into the NHR@FAU "Fritz" cluster

You will get access to the "Fritz" cluster at NHR@FAU via personalized web links, which will enable you to connect to a Jupyterhub instance.

Go to https://hub.nhr.fau.de/jupyter-training-nlpe-access.php to access the JupyterHub instance. You will see a simple web form:


Enter the email address you used to register. You will get an email with a new link to finally access the JupyterHub

A page will open with a big button to start your JupyterHub instance


After starting, you see a selection of profiles. Select Fritz:

After waiting, the server starts a terminal on the compute node.

The job that is started for you contains already the following settings:

  • -C hwperf # required for LIKWID on NHR@FAU systems)
  • --exclusive # reserve entire node
  • -c 72  # (up to) 72 threads per process
  • --cpu-freq=2400000-2400000:performance # fix clock to base CPU frequency

Open a terminal with the Terminal launcher to open a terminal on the compute node:


What happens if I close the terminal?

You should see the Launcher page of the jupyter notebook server. Open a new terminal and you are again on the compute node.


Closing the jupyter notebook server

After the course, please shut the server down.

File -> Hub Control Panel
