open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi
in mpich2 directory there is a examples sub-directory in which you should find cpi.exe
Check this program run well.
Then try to run it in parallel. The command should be something like:
..\bin\mpiexec -n 2 cpi.exe

As long as you will not be able to run this example, you will not be able to run telemac in parallel.
And the problem is not in the telemac side but linked to mpi installation on your computer and/or the configuration of mpich.

other check that could be done:
from the bin directory of mpich, try smpd -status
if smpd not running, you could try smpd -install
smpd -help will give you more informations on possibilities...
