I have read tutorials, checked mpiexmpl and examples, but all
examples use only one binary and have code like

if (rank == 0)
  do_something(for example send)
else
  do_other_thing(for example receive)

But I would like to put `do_something' and `do_other_thing' in
_different_ binaries (and start one instance of those processes).

I think MPI_Intercomm_XXX can help, but I have not found any
example of them. Do you have one?
