= '''Using libIGCM librairie with ORCA2_LIM''' = 

== A - Purposes: ==

[[BR]]


    * Document the using of libIGCM for NEMO, in configuration ORCA2_LIM

    * Define the following alias to use SVN : [[BR]]

{{{
 alias svn_ano='svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl'
 alias svn_libigcm='svn co http://forge.ipsl.jussieu.fr/libigcm/svn/tags/libIGCM_v1_1 libIGCM'
 alias svn_nemoligcm='svn co http://forge.ipsl.jussieu.fr/nemo/svn/branches/libIGCM/ORCA2_LIM/IGCM00 IGCM00'
}}}

    * Create and go to the working directory : [[BR]]

{{{
 mkdir TRY ; cd TRY
}}}

    * Extract modipsl : [[BR]]

{{{
 svn_ano 
}}}

    * Extract NEMO : [[BR]]

{{{
 cd modipsl/util 
 ./model NEMO 
}}}
   
    * Extract libigcm : [[BR]]

{{{ 
 cd ../ 
 svn_libigcm
}}}
   
    * Extract card for NEMO for libIGCM : [[BR]]

{{{ 
 cd config/ORCA2_LIM 
 svn_nemolibigcm
}}}

   * Choosing ORCA2_LIM configuration : [[BR]]

{{{
 cd ../../modeles/util 
 ./fait_config ORCA2_LIM
}}}
    Editing at this point modipsl/config/ORCA2_LIM/IGCM00/config.card

    * Install the makefiles and makejob : [[BR]]

{{{
 cd ../../util 
 ./ins_make
 ./ins_job
}}}

    * Compile : [[BR]]

{{{
 cd ../config/ORCA2_LIM 
 gmake
}}}

    * Submit Job : [[BR]]

{{{
 cd IGCM00 
 qsub Job_NL1  (on brodie.idris.fr)
}}}

=== C.1 Errors in modipsl/config/ORCA2_LIM/IGCM00/Script_Output_''Job'' ===


    * '''TERM = (vt100) ${HOME:-.}/.profile: .bashrc:  not found'''
    * '''ksh: D--------------------------------------------------------------------==:  not found'''


 it can depends on your '''.profile''' file.
  
 Everything works when your file .profile is like:

 «# .profile  (idris)
 # Fichier d environnement a charger sur la frontale TX7 unix LINUX
 # Vous pouvez mettre a jour le fichier .profile_tx
 if [ `hostname` = "brodie" -a -f $HOME/.profile_tx ]; then
 . $HOME/.profile_tx
 # Fichier d environnement a charger sur les noeuds SX8 unix SUPER-UX
 # Vous pouvez mettre a jour le fichier .profile_sx
 elif [ `hostname` != "brodie" -a -f $HOME/.profile_sx ]; then
 . $HOME/.profile_sx
 else
 echo
 fi »

    * '''Error  « cat: cannot open ........./modipsl/config/ORCA2_LIM/IGCM00/../.resol »''' :


 it is due to modipsl/libIGCM/AA_job file.
 You have to change in this way:

 #-- Resolution FLAG for oasis input
 #RESOL=$(cat ${SUBMIT_DIR}/../.resol)
 RESOL=

 (does not still fixed in libIGCM_v1_1)

    * '''Input files and BC for NEMO'''

 In this moment we've still to download '''/u/rech/eee/reee512/NEMO/ORCA2_LIM_nemo_v3.tar''' file, and to untar it into the directory:

 ${R_BC}/OCE/ORCA2_LIM

 and where  ${R_BC} is a variable that can be changed in modipsl/config/ORCA2_LIM/IGCM00/config.card file
