open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi all,

I get a segmentation fault error generated when trying to run Telemac-2D with more than one parallel processors on an HPC linux cluster (Telemac-2D runs in parallel mode when only 1 processor is denoted).

Compilation of Telemac suite is done without errors and single processor simulations complete with the test cases as input. Metis 4.0.3 library is compiled from source and successfully goes through the suggested mtest.

Both the Telemac v6p2 and Metis libraries are compiled with gcc-4.1.2 and openmpi 1.3.3. (These two are compatible on this cluster infrastructure in most applications requiring mpi libraries).

An earlier version of Telemac-2D v6p0 successfully runs in parallel mode on the same cluster with the same metis 4.0.3 libraries BUT it is compiled with the openmpi/1.3.3/intel (gcc-4.1.2 also - mpicc is the actual gcc compiler in this case).

Are you aware of any related issues and/or solutions?

Thanks in advance,

Christos

Hello,

TELEMAC v6p2 is only compatible with METIS 5.
You may have to recompile and link to that one instead.

Compilation of METIS on Linux is a piece of cake ...

Let us know if yo uhave troubles.

Hope this helps,
Sébastien.

Also, I would recommend you use gfortran 4.6.2 at least. We have known issues with file REWIND fortran command with older versions.

Good luck.
Sébastien.

The newest version of gfortran available is 4.6.1 (through gcc).

I will compile the metis 5.0 libraries and let you know of any troubles.

Thanks,

Christos
