Hi, I try to be clearer:
osa@libertas:~$ echo $LD_LIBRARY_PATH
osa@libertas:~$ echo $PATH
I compile the file with mpicc, then:
osa@libertas:~/prove/openmpi$ mpirun -np 2 es1
The comand is blocked. Don't run. CTRL+X does not end the program.
What is your program doing? Can you tell if it's getting past MPI_INIT, or even launching at all? Can you mpirun non-MPI applications, such as "hostname" and "uptime"?
This is ps output:
osa@libertas:~/prove/openmpi$ mpirun -np 2 es1 &
PID TTY TIME CMD
6135 pts/2 00:00:00 bash
6151 pts/2 00:00:00 mpirun
6153 pts/2 00:00:00 ssh
6161 pts/2 00:00:00 ps
Are you launching this es1 application locally or remotely? From your command line and previous description, I *assume* that it's local, but I see an "ssh" in your ps output, possibly meaning that mpirun has launched the application remotely (e.g., if you specified a default hostfile or somesuch).
