3. How to install your environment at IDRIS

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
    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.
    ryyy999@ada: rsh gaya pwd
    ryyy999@ada: date > a ; rcp a gaya:
  • Transfers Ada/Gaya must be done with mfget/mfput.
  • For dods access, use the command mfdods on Gaya. This creates the link (24h after the first time) visible here:
    # 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


  • 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:

4.2. Quotas

To check the used space and the size of the HOME, WORKDIR and GAYA:

# Quota HOME
ryyy999@ada: quota_u

ryyy999@ada: quota_u -w

# Quota GAYA
ryyy999@gaya: 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 Gaya:IGCM_OUT.

The IDRIS's dods server is accessible from:
