Common dynamics; keep up with updates (seq and ) in LMDZ5 (up tio rev 1845):

  • General stuff:
  • makelmdz_fcm: add options -j # (compile using # threads) and -full, and to keep up

with Earth model, possibility to compile with various versions of orchidee

  • bld.cfg: adaptations to enable compiling using multiple threads
  • build_gcm: adaptations to enable compiling using multiple threads
  • makelmdz: keep up with Earth model: possibility to compile with various versions of orchidee + cosmetic changes + library directory name change
  • bibio:
  • wxios.F90 : Added for possible future use of XIOS library
  • filtrez:
  • mkl_dft_type.f90 & mkl_dfti.f90 : MKL (for MKL FFT) interface definitions
  • filtreg_mod : limit use of FFT to parallel mode
  • mod_filtre_fft.F90 & mod_filtre_fft_lov.F90 : swich to use parallel_lmdz
  • dyn3d:
  • abort_gcm.F : add things for xios
  • advtrac.F90 : minor change in CFL outputs
  • ce0l.F90 : indicesol.h is now module indice_sol_mod
  • comvert.h : cosmetic change on comments
  • gcm.F : add xios and use module indice_sol_mod (for INCA)
  • inigeom.F : move two computations outside loop
  • dyn3dpar:
  • parallel.F90 => parallel_lmdz.F90 : and change all the "use parallel" into "use parallel_lmdz" in all files in dyn3dpar
  • comvert.h : cosmetic change on comments
  • gcm.F : add xios and use module indice_sol_mod (for INCA)
  • leapfrog_p.F : add xios + correction for times in Newtonian case
  • ce0l.F90 : indicesol.h is now module indice_sol_mod
  • inigeom.F : move two computations outside loop
