= 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
