Testing CLIMAF on ciclad

Reminder: JYP's CLIMAF installation notes

• Copy the notebooks:

  • cd somewhere/Notebooks
    cp -pr /ciclad-home/jservon/TP_CliMAF .

• Initialize the python environment you want to use:
  • standard environment: module load climaf
  • JYP's environment: we assume that the required module load and environment variables have already been initialized from ~jypmce/.bashrc
    • conda activate cdatm_py2

• Start jupyter from the TP directory:

  • cd somewhere/Notebooks/TP_CliMAF
    jupyter notebook --no-browser

    • You can also explicitly specify a port (e.g. use the one associated with your account in /ciclad-home/jservon/Evaluation/CliMAF/climaf_installs/climaf_1.2.10/bin/cmip6.notebook.txt) with
      jupyter notebook --no-browser --port=pppp_number
  • Write down the connection URL and token: http://localhost:8888/?token=9f7682071ab5d6a3e…
    • The port number may be different from the default 8888
  • When you are finished, do not forget to kill the ipython server by typing ^C^C (2x CTRL-C)

• At LSCE (or on the Windows machine where you will run the browser connecting to the server on ciclad)
  • Use Putty to start a tunnel to the jupyter server on ciclad:
    • Create a New session (or update an existing one) with the following parameters
      • Host Name: ciclad.ipsl.jussieu.fr
      • Saved Sessions (the name used to save this set of parameters): your_login @ ciclad TUNNEL
      • Connection → Data → Auto-login username: your_login
      • Connection → SSH → Tunnels
        • Source port: 8000
        • Destination: localhost:8888 (or the port number displayed when you started the server on ciclad)
        • Click on Add and you should get something like
      • Click on Session (at the top left) and then Save
      • Click on Open. This will open a Putty terminal (with the tunnel) that you have to keep open as long as you need the tunnel, and remember to close at the end of your session
      • On your local machine, open the URL you got on the server, after having replaced 8888 (or whatever the port was) with 8000 (or whatever you chose as a Source port number above)
        • http://localhost:8000/?token=9f7682071ab5d6a3e…

• If you are on a Win10 machine with WSL, a Mac or a Linux machine, you can get the same result with:
  • Open a shell and type: ssh -L 8000:localhost:8888 your_login@ciclad.ipsl.jussieu.fr
  • In a browser, open the URL with the corrected 8000 port http://localhost:8000/?token=9f7682071ab5d6a3e…

• handling of CLIMAF_LOG_DIR when it is set or not, esp last.out
• rename last.out ?
• problem with cfile when period is not set
• cdo not loaded with 'module load climaf'
• netcdf problems with some files on ciclad20
