You can not redirect stdout/stderr inside an app schema. In LAM, all
stdout and stderr from all MPI applications *always* are emitted via
mpirun's stdout and stderr.
If you need more fine grained stdout/stderr redirection, John's idea
of a shell script that is launched in your app schema that starts the
real MPI process and redirects stdout/stderr is probably your best bet.
Hope this helps,
Brian
