3. How to install your environment at IDRIS
- Find more information about IDRIS on http://www.idris.fr/eng/ and for new users here : http://www.idris.fr/static/intro/doc_nouvel_utilisateur-eng.html
- Connexion to IDRIS is possible with ssh command from a registered machine. All forms are available here : http://www.idris.fr/eng/forms/index-forms.html
- Scripts environment at IDRIS
- The Ada machine at IDRIS can be used for our configurations. It supports the model execution and post processing.
- Note: the software the Tina software installed at IDRIS gives access to hourly, daily and weekly backups of your $HOME files.
It is important to take the time to install a comfortable and efficient environment.
- We recommend to follow the example of the rpsl035 login's environment which is in bash. Don't use the default .bash_profile but use instead the ~rpsl035/.bash_login file. Copy this file to your home and remove the default .bash_profile.
ryyy999@ada: rm $HOME/.bash_profile ryyy999@ada: cp ~rpsl035/.bash_login $HOME/.
- These file include /smphome/rech/psl/rpsl035/.atlas_env_ada_intel_2013_0_bash which include
- The path of the compiling tools fcm and the rebuild tool used to reconstruct files from a parallel model:
export PATH=/smphome/rech/psl/rpsl035/FCM/bin:$PATH
- The path of the compiling tools fcm and the rebuild tool used to reconstruct files from a parallel model:
- The modules giving access to libraries and post processing tools needed on our platform.
module load netcdf (currently netcdf/seq/4.1.3 in interactive mode) module load ferret/6.85 module load nco/4.4.6 module load cdo/1.6.5
- Avoid messages displayed when connecting on Ada and Ergon. Make sure that the command rsh ergon pwd returns a unique line with the HOME on Ada. Make sure the copy of a file using rcp works properly in the two directions. Make sure that the command ssh ergon pwd returns a unique line with the HOME of ERGON on ADA.
ryyy999@ada: ssh ergon pwd /arch/home/rech/yyy/ryyy999 ryyy999@ada: date > a ; rcp a ergon:
- Transfers Ada/Ergon must be done with mfget/mfput.
- For dods access, use the command mfdods on Ergon. This creates the link (24h after the first time) visible here: http://dods.idris.fr and soon (October 2015) here : http://prodn.idris.fr/thredds/catalog/ipsl_public/catalog.html
# Export a file: ryyy999@ergon: mfdods mon_fichier -d pub/ryyy999/my_dir # Once the access activated, you must do the following to destroy a file: ryyy999@ada: mfdods -r /u/DODS/pub/ryyy999/my_dir/my_file
- To give access to the WORKDIR of Ada to all (755 or drwxr-xr-x), you must contact the IDRIS' assistance for the level /workgpfs/rech/grp.
4. Accounting
To know the computing time used by your group (updated once a day):
plab999@ada:~> cpt
5. Things to know about file systems
5.1. WORKDIR
- The $WORKDIR Ada is large but it is not saved.
- The $WORKDIR Ada can be extended (20 To for the group for example). The project investigator can ask an extension on the IDRIS's extranet. See: http://www.idris.fr/extranet.html or directly from an authorized IP : https://extranet.idris.fr/.
5.2. ERGON
- The $HOME Ergon has to be used for archiving big files
- The $HOME Ergon can be extended (300 To for the group for example). The project investigator can ask an extension on the IDRIS's extranet. See: http://www.idris.fr/extranet.html or directly from an authorized IP : https://extranet.idris.fr/.
5.3. Quotas
To check the used space and the size of the HOME, WORKDIR and ERGON:
# Quota HOME ryyy999@ada: quota_u # Quota WORKDIR ryyy999@ada: quota_u -w # Quota ERGON ryyy999@ergon: quota_u
6. Simulation outputs
Final simulation outputs are stored on Ergon in IGCM_OUT directories. There are also available from Adapp in $ARCHIVE/IGCM_OUT but not directly from Ada.
The IDRIS's dods server is accessible from: http://dods.idris.fr and soon (October 2015) here : http://prodn.idris.fr/thredds/catalog/ipsl_public/catalog.html
7. About Password
At IDRIS, you have a unique password for all computers. Password have to be changed one time per year. The command to change your password is passwd . You receive a mail 2 weeks before password expiration.
