How to make a parallel run till nemo v3_2_2

Add a cpp key and compile

and then see:

  • Add key in modipsl/config/ORCA2_LIM/scripts/BB_make.ldef :
  • Set number of processor in modipsl/modeles/NEMO/OPA_SRC/par_oce.F90 :
    set jpni, jpnj and jpnij    

  • Do an ins_make :

  • Go in ORCA2_LIM directory :
    cd modipsl/config/ORCA2_LIM
  • Compile :

Configure config.card

  • Set same number of processors at compiling time in modipsl/config/ORCA2_LIM/IGCM00/config.card: :
    #-- Total Number of Processors 
    JobNumProcTot=#proc at compiling time
  • Set a frequency for offline rebuild compatible with PeriodLength?

On brodie

  • Enable multi NQS class :
    #-- PBS Class (required on brodie mono/multi)
  • Enable run multi processors option in modipsl/config/ORCA2_LIM/IGCM00/config.card: :
    #-- Run Options :
    JobRunOptions='"-np "${BATCH_NUM_PROC_TOT}"'

On vargas

  • Change MPI send type in namelist
       cn_mpi_send =  'I'      !  mpi send/recieve type   ='S', 'B', or 'I' for standard send,
