The above syntax won't really work. With LAM/MPI, you can not specify
which host to run on by name. You can, however, use an appschema to run
on specific nodes by specifying node numbers within the LAM universe (n0,
n1, ...). I would recommend reading the lamboot(5) and mpirun(5) man
pages, as well as the tutorials on the LAM/MPI web page for more
information.
