open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi all,

I’m tring to install telemac on a Red hat OS. This is a parallel setup using Intel MPI and Intel Fortran :
⁃ Intel MPI Library for Linux, 64-bits, Version 4.1
⁃ ifort version 13.1.0
⁃ python 2.6.6 - I know that version 2.7 is recommended, but until now I can’t get it

Following the telemac setup instructions with python, I have compiled metis 4.0.3 (probably compiled with gfortran)
I setup the systel.cfg as the following:

[ifortmpi]
root: /home/xavier.thomas/telemac/v6p2r1
version: v6p2
language: 1

#

When running with PARALLELS PROCESSORS set to 1, it works fine
When I increase PARALLELS PROCESSORS to 2, I got the following error message :
$> runcode.py telemac2d -s cas -w outputdir

The last lines in the partel_T2GEO.log says :
USING ONLY METIS_PARTMESHDUAL SUBROUTINE
THE MESH PARTITIONING STEP METIS STARTS

So I have compiled metis with Intel fortran inserting CC=icc in each makefiles (Lib, Programs and Test) but it is still the same result when I launch telemac. Is anybody has an idea ?

Regards

Hello,

In v6p2 and above.
You need to use metis 5.x.x
That seems to be your problem.

Hope it helps
