OK, so I quickly rewrote the subroutine from my version of the subroutine, and it displayed the same error.

I then tried to remove the EXTERNAL déclarations and use the INTERFACE_PARALLEL module, but I still ended up with the same error.

Now that I'm thinking about it, could it be coming from the way I set the sediment concentration on the boundaries? I check the number of the boundary point to see if it belongs to my first or my second border, but I wonder if the function BOUNDARY_COLOUR() only works in sequential, as the mesh is splitted between the process when running in parallel.

Also compile a debug parallel ready configuration and try to run the computation with that configuration. Also, setting DEBUGGER=1 in your cas always helps.

Thanks for your answers. I managed to launch it (it had actually something to do with the lengths of some lines in the fortran file, which was not a problem on my personal computer but didn't work with the one dedicated to computation), however I still run into errors.

Problem is, I don't have anything about what causes the program to stop.

Also compile a debug parallel ready configuration and try to run the computation with that configuration.

What do you mean? Compile a telemac configuration?
As for the DEBUGGER=1, I've thought about it, the problem is that it creates really large files very quickly and I'm afraid I'll quickly run out of disk space... I'll see if I can give it a try though.

A debug configuration includes some extra flags to the compiler to give more messages in case of an error. For my setup with mingw-w64 it is something like this:

[gfsdbg]
#
cmd_obj:    x86_64-w64-mingw32-gfortran -cpp -march=native -g -ggdb -fbounds-check  -Wall -c -fbacktrace -finit-real=nan <mods> <incs> <f95name>
cmd_exe:    x86_64-w64-mingw32-gfortran -static -march=native -g -ggdb -fbounds-check  -Wall -v -fbacktrace -finit-real=nan -o <exename> <objs> -Xlinker --start-group <libs> 
#--end-group
#

If disk space is a problem for you output files, then maybe there isn't enough space for the actual result files, so the computation cannot continue after some point.
