Python resources

There are two options to use a Python IDE on Marenostrum:

• Connect to Marenostrum with a display software and use Spyder:

  ssh -X [email protected]
  GJDZFvH5.yyy
  salloc -J interactive --x11
  module load ANACONDA
  export XDG_RUNTIME_DIR="" 
  spyder

  Replace yyy with your account's number.

• If you don't have a display software like XQuartz, it is possible to use Jupyter notebook by ssh tunnel (this procedure is bit more complex):

  ssh [email protected]
  GJDZFvH5.yyy
  salloc --partition=interactive
  module load ANACONDA
  export XDG_RUNTIME_DIR="" 
  jupyter notebook --no-browser --ip=127.0.0.1 --port=9yyy

  Replace yyy with your account's number. As output of the last command you should receive a token for your Jupyter session of the type http://127.0.0.1:9yyy/?token=xxx….

  In another terminal on your local machine input:

  ssh -t -t [email protected] -L 7077:localhost:8088 ssh loginX -L 8088:localhost:9yyy

  Replace X with the number that you got when creating the interactive session. Open the browser on your local machine and type localhost:7077. Insert the token that you received when starting the Jupyter session.

Here you can find an introduction to Spyder and Jupyter.
