Xios in ORCHIDEE

The interface for XIOS is implemented in ORCHIDEE/trunk rev rev 1788 for usage of ORCHIDEE offline.
This page is about the on going work with XIOS in ORCHIDEE. The work with XIOS is done directly in the trunk of ORCHIDEE. Here are some notes during implementation and testing phase. Note ! All tests for now have only been done with ORCHIDEE offline mode. The implementation in ORCHIDEE will need to change when adapting to run with LMDZ.

How to install ORCHIDEE with XIOS for offline use : at CURIE

  • Extract
    > svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
    > cd modipsl/util
    
    Add following line in mod.def (take XIOS rev 446):
    #-C- ORCHIDEE_trunk  XIOS/trunk                               446     12 XIOS               modeles
    
    > ./model ORCHIDEE_trunk
    
  • Adapt compiling with netcdf parallel
    cd ../util
    # Change netcdf in modipsl/util/AA_make.gdef to following :
    
    #-Q- curie  NCDF_INC = /usr/local/netcdf-4.2_hdf5_parallel/include
    #-Q- curie  NCDF_LIB = -L/usr/local/netcdf-4.2_hdf5_parallel/lib -lnetcdff -lnetcdf -lstdc++
    
    cd ../modeles/ORCHIDEE/arch
    # Change netcdf in arch-X64_CURIE.path to following : 
    NETCDF_LIBDIR="/usr/local/netcdf-4.2_hdf5_parallel/lib -lnetcdff -lnetcdf -lstdc++"
    NETCDF_INCDIR=/usr/local/netcdf-4.2_hdf5_parallel/include
    
    # Regenerate makefiles
    cd ../../../util
    ./ins_make
    
  • Compile using fcm
    > cd ../config/ORCHIDEE_OL
    > gmake with_xios
    
  • Lance
    • The executable can now be used with XIOS or with IOIPSL or with both at the same time.
      • Activate XIOS by adding XIOS_ORCHIDEE_OK=y
      • Deactivate IOIPSL by setting WRITE_STEP=0 and STOMATE_HIST_DT=0 in run.def
    • This executable must be used with netcdf and hdf5 parallel, add in the job just before exexcution following lines :
      module unload netcdf hdf5
      module load netcdf/4.2_hdf5_parallel
      module load hdf5/1.8.9_parallel
      
    • The executable can be launched in
      • attached mode : this means that the server XIOS is not used. You only launches the orchidee_ol executable.
      • using the server xios : in this case, one or several cores are dedicated to the server and the reste to orchiee_ol.
  • Rebuild
    • If using file_definition type="multiple_file" then rebuild must be done. Use this rebuild : /ccc/cont003/home/dsm/p86ipsl/rebuild/src_X64_CURIE/modipsl_v2_2_2_netcdf4.2/bin/rebuild. For exemple :
      /ccc/cont003/home/dsm/p86ipsl/rebuild/src_X64_CURIE/modipsl_v2_2_2_netcdf4.2/bin/rebuild -o sechiba_history_xios.nc sechiba_history_xios_*
      
    • If using file_definition type="one_file" then no rebuild is needed.
  • Visulize netcdf output
    • ferret : compatible to all netcdf versions, IOIPSL and XIOS output
    • nco : all versions adapted for IOIPSL output. To vizualize XIOS output, you need to have loaded netcdf and hdf5 parallel.
    • cdo : all versions adapted for IOIPSL output. To vizualize XIOS output, you need to have loaded netcdf and hdf5 parallel and also a newer version of cdo.
    • Load following modules to use interactivly these tools :
      module unload netcdf hdf5 cdo
      module load netcdf/4.2_hdf5_parallel
      module load hdf5/1.8.9_parallel
      module load cdo/1.6.0
