CONTROL key_mpp_mpi

  • Control that you have in your cpp_ORCA2_LIM3.fcm file key_mpp_mpi (normally it is present by default): 

Configure config.card

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

On ada

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