Please read the DYNAMICO installation process first.

Compiling DYNAMICO with a LMDZ physics package

Once you have downloaded DYNAMICO into the ICOSAGCM/ folder, go to the ICOSA_LMDZ folder and compile there using one of the compile example files:

• compile_adastra-gnu
• compile_irene-amd

It might be wise to make a copy, i.e.:

cp compile_adastra-gnu compile

You can then edit the file to match your architecture (the arch parameter). The file should look like this:

arch=ifort_MESOIPSL # change according to your arch file

# Gas Giants/generic:
make_icosa_lmdz -p std -p_opt "-b 17x23" -parallel mpi -arch ${arch} -arch_path ../ARCH -job 8  -full #-nodeps

# Venus:
#make_icosa_lmdz -p venus -parallel mpi -arch ${arch} -arch_path ../ARCH -job 8 -full #-nodeps

# Mars:
# make_icosa_lmdz -p mars -parallel mpi -arch ${arch} -arch_path ../ARCH -job 8 -full #-nodeps

# Pluto:
# make_icosa_lmdz -p pluto -p_opt "-b 17x23" -parallel mpi -arch ${arch} -arch_path ../ARCH -job 8 -full #-nodeps

You can change the options such as the parallel version you will use (-parallel mpi or mpi_omp) and the parameters for the physics package (with the -p_opt options, for example -d 48x32x50 to specify a resolution, see Quick_Install_and_Run#Compiling_the_GCM).

Using the -full option, the script make_icosa_lmdz will compile:

• IOIPSL
• XIOS
• LMDZ.COMMON (your physics)
• ICOSAGCM (DYNAMICO)

and then link everything in the ICOSA_LMDZ/bin folder, under the name of the executable icosa_lmdz.exe.

If you use the -nodeps option, XIOS and IOIPSL will *not* be compiled.

The script should stop at each step of the compilation if it fails (for example the compilation of the physics package).

You can also compile each step on its own and remove the -full option (you can keep the -nodeps option) (please click on each package name for its page).

Known issues

If you obtain an error of the type:

XIOS/src/io/netcdf.hpp:20:12: fatal error: netcdf_par.h: Aucun fichier ou dossier de ce nom
   20 | #  include <netcdf_par.h>
      |            ^~~~~~~~~~~~~~
compilation terminated.

This is due to the parallel version of netcdf not being recognized by the compilation module, typically for XIOS. In that case, please open the arch.path file used by the module and change the path pointing to netcdf_par.h. The default path should look like this:

NETCDF_INCDIR="$(nc-config --cflags) $(nf-config --fflags) -I/usr/lib/x86_64-linux-gnu/netcdf/mpi/include"

You can find the path where netcdf_par.h is located via:

locate netcdf_par.h

And you can set the new_path found (without netcdf_par.h) like this:

NETCDF_INCDIR="$(nc-config --cflags) $(nf-config --fflags) -Inew_path"

Running DYNAMICO with a physics package
