Hello,

I have compiled the Telemac system of v6p3r2 using ifortdebianmpi configuration, adopted from Dr. Pat' post with modifications. It runs well with a telemac2d test case in scalar mode, but not in parallel. The configuration file is also attached.

Suggestions to fix this error are really appreciated.

Many thanks,
Amyrhul

Hi,

Try commenting the statement on line no. 32
#mpi_cmdexec:  /software/libraries/openmpi/1.5.4/gnu-4.6.2/bin/mpiexec -machinefile MPI_HOSTFILE -np <ncsize> <exename>

Hope this helps,

With Best regards,
Gourish

Hello Gourish,

Thank you so much. As you said, now it's working in parallel mode.
