The MPI dynamic process capability in LAM 6.0 would do the job,
in particular the MPIL_Spawn() extension function.  The function
generates an inter-communicator that allows the parents and children
to communicate, as specified in MPI-2.

An MPI_Spawn() function (no L) and many related functions including
the client/server capability, all conforming to the current (and
hopefully close to final) draft of the MPI-2 dynamic process chapter,
will be released with LAM 6.1, real-soon-now (tm).
