It is important to take the time to install a comfortable and efficient environment.
We suggest the user to use the p86ipsl login's environment (in bash) as an example (copy the ~p86ipsl/.bashrc_curie and the ~p86ipsl/.bash_profile files in your home). You can complete the .bashrc file to create your favorite environment (alias, module load ...)
ryyy999@curie: cp ~p86ipsl/.bashrc_curie ~/. ryyy999@curie: cp ~p86ipsl/.bash_profile ~/.
WARNING : if you have a ~/.profile file, it's better to remove it to avoid any problem during the execution of a simulation with libIGCM
In this environment is specified:
export PATH=~p86ipsl/fcm/bin:~p86ipsl/rebuild/src_X64_CURIE/modipsl_v2_2_2_netcdf4.2/bin/rebuild:$PATH
module load ghostscript/9.04 module load ferret/6.9.3 module load gsl/1.14 module load netcdf/4.3.3.1_hdf5_parallel module load cdo/1.6.7 module load imagemagick/6.7.4 module load nco/4.4.8
ryyy999@curie: ccc_myproject
#MSUB -A genxxx
To check the available and used storage capacities of HOME, SCRATCH, CCCWORKDIR and CCCSTOREDIR:
ryyy999@curie: ccc_quota
On the curie machine this command will also return the space used by scratch (a specificity of the curie machine).
This command has been improved and gives a lot of information : quotas and usage of shared space, type and duration of exception.
The $SCRATCHDIRdirectory is often cleaned and only files that are less than 40 days are stored.
The $CCCWORKDIR directory corresponds to the $WORKDIR directory on curie. It is large but its content is not backed up. Don't forget to do a backup (tar) for important directories.
To manipulate the files in /ccc/store a few commands are useful:
# Demigrate a list of files on CCCSTOREDIR, see also "ccc_hsm -h" ccc_hsm get $CCCSTOREDIR/FILE1 $CCCSTOREDIR/FILE2 ... # Demigrate recursively the files from a CCCSTOREDIR directory, see also "ccc_hsm -h" ccc_hsm get -r $CCCSTOREDIR/DIRECTORY # Find out the used space on CCCSTOREDIR cd $CCCSTOREDIR ; find . -printf "%y %s %p \n" | \ awk '{ SUM+=$2 } END {print "SUM " SUM/1000000 " Mo " SUM/1000000000 " Go" }' # or use --apparent-size with du : du -sh --apparent-size
ccc_home could help you to find directory complete pathname for an other user or for you .
>ccc_home -h
ccc_home: Print the path of a user directory (default: home directory).
usage: ccc_home [ -H | -s | -t | -W | -A | -G | -a] [-u user]
[-h, --help]
-H, --home : (default) print the home directory path ($HOME)
-s, -t, --scratch : print the scratch directory path ($SCRATCHDIR)
-W, --cccwork : print the CCC work directory path ($CCCWORKDIR)
-A, --cccstore : print the CCC store directory path ($CCCSTOREDIR)
-G, --cccgenostore : print the CCC genostore directory path ($CCCGENOSTOREDIR)
-a, --all : print all paths
-u user : show paths for the specified user instead of the current user
-h, --help : display this help and exit
> ccc_home -A -u ryyy999

To store a file for the first time on esgf/thredds, you must ask for esgf/thredds write access by mail to the TGCC hotline access : hotline.tgcc@cea.fr.

For gencmip6 project, and only for it, 3 more file systems and 4 more directories are available. Phase 1 have been installed in april 2016. Phase 2 and Phase 3 will come later in 2017 and 2018.
To use them, in interactive mode, you have to do : module load datadir/gencmip6.
Since libIGCM_v2.8.1, if you set your project to gencmip6/devcmip6, they are automatically used in place of usual HOME, CCCWORKDIR, CCCSTOREDIR and SCRATCHDIR : module switch dfldatadir dfldatadir/gencmip6 called from libIGCM.

To receive the end-of-job messages sent by the job itself: end of simulation, error,... you must specify your address in the $HOME/.forward file.
Final simulation outputs are stored in $CCCSTOREDIR/IGCM_OUT and on $CCCWORKDIR/IGCM_OUT regarding the ATLAS and MONITORING directories.
