How you run that command line from *inside a Torque* job?

Ah, gotcha.
I'm guessing that you're running OMPI outside of a Torque job, and
that's why it's running entirely on a single machine (or on the
machines where you listed in a hostfile).
You need to run your Open MPI job inside the Torque job that you
submit; OMPI should then detect that it is inside a Torque job and
automatically use the hosts that have been allocated by Torque.
You probably want to consult your local sysadmin / cluster admin to
help you get Torque setup in your account, show you how to submit job
scripts, etc. (the specific instructions for how to use Torque can
vary from site to site and are a bit outside the scope of this list).
Good luck!
