  Does anyone know of implementations of MPI which allow
you start MPI from within a subroutine (i.e. not using something
like mpirun).

  The reason I ask is that I have an application which is
written in a highly level interpreted language and dynamically
calls a precompiled subroutine to execute a particularly
computationally intensive step of the program.  I would like
it if within this subroutine I could break down the problem
even further and run it on multiple processors, but this requires
starting MPI from within the subroutine.
