Yup, this should work. Just do:

  $ mpd &

  $ mpiexec -n 16 ./my_app

If you use mpd without mpdboot, you don't need to worry about what your 
hostname is (it'll take whatever your hostname command returns).

If you want to, you can use gforker as well. You'll need to reconfigure 
mpich2 for that using --with-pm=gforker for that.
