Hi
I don't understand why it is a problem to copy a single script to your nodes -
wouldn't the following shell-script work?
#!/bin/sh
for num in `seq 128`
do
scp new_script username@host_$num:path/to/workdir/
done

I got it, but I would like to be able to do it without creating/copying new

I think you missed Matt's point -- he was suggesting writing a single
script that just reacts accordingly to which host it is on and sets
the environment variable before launching your back-end MPI
executable. Specifically, instead of:
mpirun ... my_mpi_app
you would do
mpirun ... script
perhaps you could use the Open-MPI environment variables
OMPI_COMM_WORLD_RANK
OMPI_COMM_WORLD_LOCAL_RANK
to construct your own environment variables?
(for versions >= 1.3)

Matt,
Thanks for your solution, but I thought about that and it is not really
convenient in my configuration to change the executable on each node.
I would like to change only mpirun command.

I typically use a script for things like this. So instead of
specifying your executable directly
