Notebooks

Try out the following if you want to run a Jupyter Notebook on the MOGON clusters, but want to run the browser locally.

1. Open a new terminal on your local computer and perform a regular login to MOGON
   

   ssh mogon

2. Now load the proper module and create an interactive job
   

   module load tools/IPython
   srun -A <account> -p <partition> -t <time>  --pty bash -i

3. Once the resources are granted, launch the Jupyter notebook on the compute node, e.g. with --port 8888:

   jupyter notebook --no-browser --port <portB>

   You should get an similar output to the following:

   To access the notebook, open this file in a browser:
           file:///gpfs/fs1/home/<username>/.local/share/jupyter/runtime/nbserver-00001-open.html
       Or copy and paste one of these URLs:
           http://<ComputeNode.mogon>:<portB>/?token=<unique token>
        or http://127.0.0.1:<portB>/?token=<unique token>
    

4. You will need to subsequently log in using a different terminal on your local computer:
   

   ssh -t mogon -L <portA>:<ComputeNode.mogon>:<portB>

   1. where <portA> needs to be unique. A reasonable suggestion is to choose the first four digits from your user id, e.g.:
      • id -u $USER or id -u $USER | cut -c1-4
      • ssh -t mogon -L $(id -u $USER | cut -c1-4):<ComputeNode.mogon>:<portB>
5. You can then enter localhost:<portA> into your browser's address bar. Jupyter will then ask you to provide the token, which you can copy & paste from the first terminal output. This is given here as <unique token>.
