Using libIGCM library with ORCA2_LIM for nemo_v3_6

Purposes

Through libIGCM give an example of run of configuration ORCA1_LIM3_PISCES with :

  • INTERANNUAL forcing files COREII (yeras from 1948 to 2009, repeted 3 times)
  • output 1Y for ocean, 1M for ice
  • RESTARTS every year
  • on Idris ADA machine

Official documentation of Libigcm is :

https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/Doc

Quick start guide : downloading nemo_3_6_STABLE:

https://forge.ipsl.jussieu.fr/nemo/browser/branches/2015/nemo_v3_6_STABLE/NEMOGCM

default setting of ORCA_LIM3 configuration in NEMO v3_6_STABLE are :

  • climatological run, with bulk core forcing, focring files COREII,
  • with calendar type noleap
  • and ocean output frequency 1Y,1M,5D,1D, ice output frequency 5D,
  • without MONITORING, and ATLAS.
  • Define the following alias to use SVN :
     alias svn_ano='svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl'
    
    
  • Create and go into working directory :
     mkdir TP-NEMO-libIGCM ; cd TP-NEMO-libIGCM
    
    
  • Extract modipsl (modipsl/libIGCM : the latest revision of tags/libIGCM_v2.6 from repository http://forge.ipsl.jussieu.fr/libigcm/svn : )
     svn_ano
    
  • Extract NEMOGCM :
    cd modipsl/util    **
     ./model NEMO_v6
    

    (verify NEMOGCM revision in modipsl/util/mod.def file: (fixed revision of NEMO: 5618)
    • #-H- NEMO_v6 NEMOGCM for CMIP6 exercise
      #-H- NEMO_v6 libIGCM tag libIGCM_v2.6
      #-M- NEMO_v6 Christian.Ethe@…
      #-C- NEMO_v6 tags/libIGCM_v2.6 HEAD 10 libIGCM .
      #-C- NEMO_v6 branches/2015/nemo_v3_6_STABLE/NEMOGCM 5618 7 . modeles
      #-C- NEMO_v6 CONFIG/UNIFORM/v6/NEMO_v6 HEAD 8 NEMO_v6 config
      )
  • Choose and compile configuration (for example if you run ORCA1_LIM configuration on "ada" machine at idris) : (ref config??? ORCA2_LIM3_PISCES?????)
     cd ../modeles/NEMOGCM/CONFIG
     ./makenemo -m X64_ADA -n ORCA1_LIM3_PISCES -r ORCA2_LIM3 -j8
    
     (executable is created in ORCA1_LIM/BLD/bin directory)
    

Using ./makenemo -h to see help ( to see list of compilers availables, to see options,...)

  • Editing at this point config/ORCA2_LIM/IGCM00/config.card (according to iodef.xml file)

NOTE : for ada ( idris ) machine starting from revision 2021 of trunk of libigcm it is possible to add in [Post] section of config.card options
[Post]
SpaceName? =PROD (to have IGCM_OUT on gaya)
PackFrequency? =10Y (to have pack option; i.e. only one tar file)

  • Editing at this point config/ORCA2_LIM/IGCM00/COMP/opa9.card
  • Editing at this point config/ORCA2_LIM/IGCM00/COMP/lim2.card

see : setupsimupage

  • Submit Job :
    cd ../     (back into modipsl directory) 
    
    ./util/ins_job
     cd ../config/ORCA2_LIM/IGCM00 
     llsubmit Job_Name
