Using libIGCM library with ORCA2_LIM for nemo_v3_6


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 :

Quick start guide : downloading nemo_3_6_STABLE:

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 modipsl'
  • Create and go into working directory :
     mkdir TP-NEMO-libIGCM ; cd TP-NEMO-libIGCM
  • Extract modipsl :
  • Extract NEMOGCM : (look at NEMOGCM definition in modipsl/util/mod.def file which branch you have:

  • modipsl/libIGCM : the latest revision of tags/libIGCM_v2.6 from repository
     cd modipsl/util 
     ./model NEMOGCM
  • Choose and compile configuration (for example if you run ORCA2_LIM configuration on "ada" machine at idris) :
     cd ../modeles/NEMOGCM/CONFIG
     ./makenemo -m x3750_ADA -n ORCA2_LIM -j8
     (executable is created in ORCA2_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
Space Name? =PROD (to have IGCM_OUT on gaya)
Pack Frequency? =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) 
     cd ../config/ORCA2_LIM/IGCM00 
     llsubmit Job_Name
