LAM: Running Octave Programs with MPI

I recently had mpitb installed on a SGI Altix system in my University in hopes to running Octave in Parallel.  Everything seems installed properly, however I am having trouble running Octave applications with mpirun.  One example is the Hello World example.  Mpitb says to run it using the command: mpirun -c 2 octave -q --eval Hello.
mpirun does not seem to like to run an application through Octave however.  It gives an error saying that octave is not an executable (it is looking to run a file directly).  I also used a simple expression like: mpirun -np 2 octave Hello.  This did not work either.  Any ideas?

Thanks,
Mike

Can you run octave without the mpirun part?  This usually
means that  
the command you are trying to run either can't properly
execute on  
the current architecture or is not found in your path.

Hope this helps,

Brian
