====== Testing CLIMAF on ciclad ======

Reminder: [[other:uvcdat:cdat_conda:climaf_install|JYP's CLIMAF installation notes]]

  * Copy the notebooks:
    * <code>cd somewhere/Notebooks
cp -pr /ciclad-home/jservon/TP_CliMAF .</code>
  * 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:
    * <code>cd somewhere/Notebooks/TP_CliMAF
jupyter notebook --no-browser</code>
      * 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, <wrap em>do not forget to kill the ipython server</wrap> 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 [[https://www.chiark.greenend.org.uk/~sgtatham/putty/|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 <wrap em>the port number displayed when you started the server on ciclad</wrap>)
          * Click on //Add// and you should get something like{{:other:uvcdat:cdat_conda:puttytunnel.png?300|}}
        * 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, <wrap em>after having replaced 8888 (or whatever the port was) with 8000</wrap> (or whatever you chose as a Source port number above)
          * ''http://localhost:8000/?token=9f7682071ab5d6a3e...''

  * If you are on a Win10 machine with [[other:win10wsl|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 <wrap em>with the corrected 8000 port</wrap> ''http://localhost:8000/?token=9f7682071ab5d6a3e...''

===== Notes to clean =====

<code>/ciclad-home/jservon/Evaluation/CliMAF/climaf_installs/climaf_1.2.10/bin/climaf-notebook

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

===== 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
