This is confusing to me.

Other than MPI_COMM_SPAWN[_MULTIPLE], we don't expose the underlying run-time
to MPI applications.
There is a whole programatic interface for the layer under MPI (the Open MPI
Runtime Environment -- ORTE), though. We don't advise mixing ORTE calls in MPI
applications, but it is certainly feasi
you could spawn more processes from currently running processes.

Hi,
One typically uses mpirun to launch a set of mpi processes.
Is there some programmatical interface to launching the runtime and having
the process that launched the runtime becoming part of the list of mpi
processes,
