Yes, the syntax is wrong in the email, but I write it correctly when I launch mpirun. When some communicating processes are on the same node the application don't terminate, otherwise the application terminate and its results are correct. My OpenMPI version is 1.2.7.

When 2 processes share a node and use shared memory for exchanges messages, my application don't terminate. At shell I write "mpirun -nolocal --mca self,sm,tcp ... (forces interface to eth0)... -np (number of processes) executable arguments".

That's not right. If you want the apps to use shared memory, you don't have to do anything. However, if you do want to specify, then the correct syntax is

mpirun -mca btl self,sm,tcp
