Last change on this file since 1264 was 1222, checked in by Ehouarn Millour, 15 years ago

Changes and cleanups to enable compiling without physics
and without ioipsl.

IOIPSL related cleanups:

  • bibio/writehist.F encapsulate the routine (which needs IOIPSL to function)

with #ifdef IOIPSL flag.

  • dyn3d/abort_gcm.F, dyn3dpar/abort_gcm.F and dyn3dpar/getparam.F90: use ioipsl_getincom module when not compiling with IOIPSL library, in order to always be able to use getin() routine.
  • removed unused "use IOIPSL" in dyn3dpar/guide_p_mod.F90
  • calendar related issue: Initialize day_ref and annee_ref in iniacademic.F (i.e. when they are not read from start.nc file)

Earth-specific programs/routines/modules:
create_etat0.F, fluxstokenc.F, limit_netcdf.F, startvar.F
(versions in dyn3d and dyn3dpar)
These routines and modules, which by design and porpose are made to function with
Earth physics are encapsulated with #CPP_EARTH cpp flag.

Earth-specific instructions:

  • calls to qminimum (specific treatment of first 2 tracers, i.e. water) in dyn3d/caladvtrac.F, dyn3d/integrd.F, dyn3dpar/caladvtrac_p.F, dyn3dpar/integrd_p.F only if (planet_type == 'earth')

Interaction with parallel physics:

  • routine dyn3dpar/parallel.F90 uses "surface_data" module (which is in the physics ...) to know value of "type_ocean" . Encapsulated that with #ifdef CPP_EARTH and set to a default type_ocean="dummy" otherwise.
  • So far, only Earth physics are parallelized, so all the interaction between parallel dynamics and parallel physics are encapsulated with #ifdef CCP_EARTH (this way we can run parallel without any physics). The (dyn3dpar) routines which contains such interaction are: bands.F90, gr_dyn_fi_p.F, gr_fi_dyn_p.F, mod_interface_dyn_phys.F90 This should later (when improving dyn/phys interface) be encapsulated with a more general and appropriate #ifdef CPP_PHYS cpp flag.

I checked that these changes do not alter results (on the simple
32x24x11 bench) on Ciclad (seq & mpi), Brodie (seq, mpi & omp) and
Vargas (seq, mpi & omp).
