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)
  • If you are on a Win10 machine with WSL, a Mac or a Linux machine, you can get the same result with:

Notes to clean

Login to ciclad
Start an interactive session on a cluster node: qsub -IVX -l mem=9g,vmem=9g,walltime=06:00:00
dig a tunnel from local machine to node: ssh -L 7225:cicladNNN:7225 jypmce@ciclad2.ipsl.jussieu.fr
init conda environment: conda activate cdatm_py2
start notebook: jupyter notebook --no-browser --port=7225 --ip=cicladNNN

(cdatm_py2) [jypmce@ciclad20 ~]$ jupyter notebook --no-browser --port=7225 --ip=ciclad20

[I 14:21:06.344 NotebookApp] [nb_conda] enabled
[I 14:21:06.352 NotebookApp] Serving notebooks from local directory: /home/jypmce
[I 14:21:06.352 NotebookApp] The Jupyter Notebook is running at:
[I 14:21:06.352 NotebookApp] http://ciclad20:7225/?token=832aa384170471352b2a36444f610e54f2e16fde383a6741

Issues to report

  • 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
