Exactly what version of Open MPI are you using? You mentioned "1.3"
-- did you download a nightly tarball at some point, or do you have an
SVN checkout? Since you have a development copy of Open MPI, it is
possible that your copy is simply broken (sorry; we *do* break the
development head every once in a while...). Can you update?
Note that Josh just made some FT fixes on the trunk today that aren't
on the v1.3 branch yet; they'll likely take a day or three to get there.

Hi, this is my openmpi-default-hostfile:
127.0.0.1 slots=2
If I invoke comand CTRL+C the application is not killed.
With mpirun -np 1 uptime the comand is ever blocked.
The comand is blocked with any comand, also comands not existent.
Thanks.

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

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).
