Working at IDRIS
Index du chapitre
1. IDRIS presentation
News : On 1/7/2014 file server gaya is read only and ergon is the new file server. More information here : http://www.idris.fr/ergon/
2. IDRIS's machines and file systems
3. How to install your environment at IDRIS
- Find more information about IDRIS on http://www.idris.fr/
- 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 $HOME files.
It is important to take the time to install a comfortable and efficient environment.
- We recommend to follow the example of the rpsl035 login's environment which is in bash. See the ~rpsl035/.bash_login file
ryyy999@ada: cat ~/.bash_login #------------------------------------------------------ # PLATFORM ENVIRONMENT #------------------------------------------------------ source ~rpsl035/.bash_login
- Enter here the path of the compiling tools fcm and the rebuild tool used to reconstruct files from a parallel model:
export PATH=/smphome/rech/psl/rpsl035/FCM/bin:$PATH
- Load here the modules giving access to libraries and post processing tools needed on our platform.
module load netcdf module load ferret/6.72 module load nco module load cdo
- Avoid messages displayed when connecting on Ada and Gaya. Make sure that the command rsh gaya 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.
- dods files not tested on Ergon. (July 2014)
- For dods access, use the command mfdods on Gaya. This creates the link (24h after the first time) visible here: http://dods.idris.fr
# Export a file: ryyy999@gaya: mfdods mon_fichier -d /cache[n]/DODS/pub/rlab001/rep_1 # Once the access activated, you must do the following to destroy a file: ryyy999@ada: mfdods -r /cache[n]/DODS/pub/rlab001/rep_1/mon_fichier
- 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.
3.1. System requirements
To know the computing time used by your group (updated once a day):
rces452@ada338:~> cpt
4. Things to know about file systems
4.1. 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/index.html.
4.2. 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
5. End-of-job messages
To receive the end-of-job messages sent by the job itself (e.g. end of simulation, errors,...) you must specify your address in the $HOME/.forward file.
6. Simulation outputs
Simulation outputs are stored on Ergon:IGCM_OUT.
The IDRIS's dods server is accessible from: http://www.idris.fr
