Hi, I try to be clearer:
osa@libertas:~$ echo $LD_LIBRARY_PATH
/usr/local/lib:/home/osa/blcr/lib
osa@libertas:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/osa/blcr/bin

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.

Try ctrl-c -- that's usually the way to kill applications that appear to have been hung.

This is ps output:

osa@libertas:~/prove/openmpi$ mpirun -np 2 es1 &
[1] 6151
osa@libertas:~/prove/openmpi$ ps
 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

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"?

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).
