I did the changes you asked and compilation completed successfully. However, the run did not complete, as before. Here are the files you asked (plus the output from partel):

Hi,

Could you try to launch the executable from the temporary directory.
Just type the command you got at the end of the file t2d_201_wing64mpi.txt

Hello,

I did that and it made no difference, the run failed again. In the meantime, I went through the gfortran manual and found the following:

1. mpif90.exe applies only to linux
2. In order to compile openmp code in gfortran, the '-fopenmp' flag should be added.

I did add the flag like it is shown below, compiled the code, but again no success.
cmd_obj:    x86_64-w64-mingw32-gfortran -c -O3 -ffixed-line-length-132 -fconvert=big-endian -frecord-marker=4 <mods> <incs> <f95name>
cmd_lib:    ar cru <libname> <objs>
cmd_exe:    x86_64-w64-mingw32-gfortran -fopenmp -fconvert=big-endian -frecord-marker=4 -v -o  <exename> <objs> -Xlinker --start-group <libs>

I have no programming knowledge, so there is little I can do from here. I hope somebody else has a go at it.

This is weird.
You don't have an error message when you tried to run manually it in the temporary folder?
In the v6p2 the error handling was not efficient so sometimes some error got lost.

The only cause i could think of is if your mpi was not compile with the same compiler as the rest of your code.

I got absolutely no error. It just returned to the dos prompt after a couple of seconds. I cannot think of a way 2 different compilers could be used in my case. PATH envar is carefully set.

I have tried to compile in parallel the fortran example in the mpich2 folder (fpi.f) and although it runs in serial mode, when I try to execute with mpiexec, it fails.

The first time I tried to run the fpi.exe, windows asked me for a firewall exemption (I authorized and it never asked again). Maybe it is a firewall issue that interferes with the execution of telemac as well. The thing is that the parallel version with Intel fortran runs OK...

Has anybody managed to compile successfully telemac with gfortran/mpich2/windows? I would be crucial to know if it is a general issue, or something that has to do with my computer/configuration/installation/gfortran version etc.

The thing is that mpi is not a compiler on its own it is just a wrapper on the compiler you use to install it.
So if mpi was installed with a different compiler...

I hope you can find someone in the community who manages to solve that.

Hi,

What about the authentification procedure?

Did you register both your username and password with wmpiregister.exe? What about your passphrase?
You can also force smpd.exe to restart with "smpd -remove" and then "smpd -install". You can also play with wmpiconfig & wmpiregister.

Anyway, fpi has to work before trying to run openTelemac in parallel.

Hi, thanks for your help.

I run the
mpiexec -validate
command and I get a SUCCESS message, so I believe it is not an authentication issue. Furthermore, the Intel Fortran compiled version of telemac runs in parallel without a problem. It's the gfortran that doesn't.

Hello,

Today I can confirm that I have managed to run validation cases in parallel, using gfortran in Windows environment. The problems I described in the previous posts don't occur any more without actually changing something. Maybe a reboot of the PC cleared a configuration issue and I never tested the parallel installation until today. I will make a separate post with my configuration so that others can confirm.

Hello,
I have also been trying to get a Windows x64 machine that currently works in Scalar Mode to run in Parallel. Recompiling with MAKEPAR90 results in several errors, with one repetative error being it cannot find parallelV6P2.lib. Is something going wrong early in the compilation that prevents that library from being set up?

I am using GFortran, and am still using PERL.
