Thank you Jeff. Now with the following commands starts, but it gets
blocked before starting. May be this problem of firewalls? Do I need
both that M1 and M2 can log into the other machine through ssh?

Thank you!

# mpirun -v -display-map -np 1 -host localhost ./init_barrier_fini : -np
1 -host
M2 /home/Computational/harald/tests/mpi/multi-machine/init_barrier_fini
