open TELEMAC-MASCARET The mathematically superior suite of solvers

Using -DHAVE_MPICH will not work it will compile but the code will not work in parallel.

-DHAVE_MPI means that we enable part of the source code that contains call to mpi function.

so it should be a problem for me to deal with (but on V7p2), including "Parmetis Support" in another post.

-DHAVE_MPI works with both mpich and openmpi

Thanks.

As many new features I would like to test on V7p2, I would like to see if you have successfully compiled this version on Linux (e.g Mint) and Windows.

Could you share with me an example of successful parallel configuration V7p2?

You can check in configs/systel.edf.cfg C9.gfortran.dyn and winHPC both worked. They are using environment variable for external libraries.

Thanks.

I see this file for V7.2, and I will try to adapt it.

By the way, could you explain a bit about "using environment variable for external libraries"?

Best Regards
Huy

All the path for med, metis, hdf5, mumps I use in the systel.edf.cfg.
Are referenced via $MEDHOME and so on.

To see how they are defined you can have a look at configs/pysource.template.sh

Dear Tran,

the keyword "DHAVE_MPI" is actually a compilation directive which tells gfortran to compile Telemac code with MPI supported and therefore produce the according binary file executable in the parallel mode. If you neglect the key word, MPI statements embedded in the Telemac code will be ignored by the compiler, i.e gfortran. As the result the final binary can only run in the scalar mode.
A point to be clear is that "DHAVE_MPI" is not a buitl-in instruction of gfortran, but a compiler switch added by the authors. That may answer why we could not find explanations about "DHAVE_MPI" in the manual of gfortran. I would recommend you to search for "DHAVE_MPI" using grep in the source folder as in the following command:
$ grep -rnw 'OpenTelemac/v6p3r2/sources' -e "DHAVE_MPI"
See ya,
Dzung

give a solution¡¡

Could you post this file "/home/mishel/telemac/v7p1/configs/systel.ubuntu.cfg" ?
And the command you ran.
