Code_Aster release : STA11.4 on OpenSUSE 12.3 64 bits - EDF/Intel version
Replied by Claus on topic Re:saturne stopped working - pls help
well yeah, it reads
[code:1]
# Chemins et librairies pour MPI
CS_MPI_PATH=/opt/saturne-1.3.2/opt/openmpi-1.2.6/arch/Linux/bin
export CS_MPI_PATH
[/code:1]
'ls $CS_MPI_PATH' show the correct content.
and this:
[code:1]
claus@kafka:~$ mpirun
mpirun (Open MPI) 1.2.6
[/code:1]
[code:1]
claus@kafka:~$ which mpirun
/usr/local/bin/mpirun
[/code:1]
Remember that I installed openmpi-1.2.6 system-wide yesterday.
just before posting this, I reinstalled openmpi-1.2.6 into /opt/sat../opt etc. and tried running a 2-core calculation. Same error.
Do you know of a way to check the functionality of openmpi? test-script/program etc.?
I don't know what else to try right now.

Hello,
I've been away from the forum for a while... sorry!
An idea came to my mind on your problem (if you still have it):
Could you check the coherency between the mpirun script Code_Saturne is using and the libraries it is linked with.
To check the MPI wrapper, please source Code_Saturne 1.3.2 cs_profile script; then, type[code:1]which mpirun[/code:1].
To check the libraries, launch a calculation (make sure that the Code_Saturne version used in the script is indeed 1.3.2); then, type[code:1]ldd cs13.exe[/code:1]in the temporary directory where Code_Saturne runs the calculation. You should especially have a look to the libmpi, libopen-rte and libopen-pal libraries (they are from the OpenMPI distribution).
Finally, you can check if both paths are coherent.
As for the tests to check if a MPI distribution works, you usually find some within the distribution (sometimes it is a simple file you have to compile and run with mpirun).
