Configuration IPSLCM5

IPSLCM5 is the IPSL coupled configuration based on NEMO as oceanic component.

First tests - April 2008

Steps

• mod.def update : to include IPSLCM5 configuration
  • mod.def : IPSLCM5 added
  • model (WORK stuff suppressed for IPSLCM5)
  • fait_config : IPSLCM5 config added
  • KEY2 adapted in IPSLCM5/AA_make
    • Pb: P_P filled in IPSLCM5/AA_make not known in Makefile.
      • Q: How to parametrize ORCA resolution and ORCA keys in IPSLCM5/AA_make?
      • A: use P_NEMO in IPSLCM5/AA_make and use P_P := $(P_NEMO:%=$(prefix)%) in scripts/BB_make
    • How to add 2 parameters in ORCA compilation : PSMILE Include and PSMILE library
  • Prefix for preprocessing added in IPSLCM5/scripts/BB_make.ldef (-D).
• CONFIG/IPSLCM5 : to prepare files used for IPSLCM5
  • components compilation :
    • fait_config update for IPSLCM5 configuration
    • AA_make for compilation
  • files required for an execution
    • logical links to similar files handled through IPSLCM4_v2
      • COMP : lmdz.card, lmdz.driver, orchidee.card, orchidee.driver
      • PARAM : Bands*, cf_name.txt, *.def
    • physical files for files used by NEMO
      • AA_make, AA_make.ldef
      • COMP: lim.card, lim.driver, opa.card, opa.driver, oasis.card, oasis.driver
      • PARAM : *param (namelist pour LIM aussi), nacouple*, namelist*
• NEMO sources modified to compile. copied from Arnaud's directory : /work/cont003/p86caub/IPSLCM4_v2_NEMO/modipsl/modeles/NEMO
  • cpl_oasis3.F90
  • restart.F90 (eviter d'appeler le fichier de restart : restart)
  • cpl.F90
  • cpl_oasis3.F90
  • tau_oasis_ice.h90
  • taumod.F90
  • flx_oasis_ice.h90
  • flxmod.F90
  • flx_oce.F90 (use mod_diurnalcycle suppressed)
  • traqsr.F90
  • trasbc.F90
  • step.F90 (use diawript suppressed)
  • opa.F90

Open questions

• Cecill licences
• User recording in NEMO and other components databases
• Minimize the number of password required
