Okay...this isn't a performance summary or anything like that. Its
just some information on what I was able to get to work. With a
couple of suggestions from Brian Barrett about building OMPI with
static libraries (possible problem with GNU libtool support for the
Intel compiler on OS X?).
Thanks.

yes for a single master this should be the same, but never try this.

Thank you for the clarification. Why is MPI_COMM_SELF not the correct
communicator for MPI_Comm_spawn(). My application will have a single master
only.
Also, can I merge the intercommunicator into an intracommunicator via
MPI_Intercomm_merge(intercomm, 0, &intracomm) and use MPI_Bcast(..., 0,
int
hi,
yes sorry for my first reply, my words were to rough.
a bcast for a intercomm works this way (in your words):
- your masters want to send a buffer to your slaves
- one of the masters must provide the MPI_ROOT as root in the MPI_BCAST call
- all slaves must provide the rank of this MPI_ROOT a
I don't think I blamed the implementation in any way in my original email.
My intent is to gain understanding of why my code does/should not work. I
assumed that I was not passing the correct intercommunicator. However, I am
at a loss on how to construct a proper intercommunicator in this case. Yo

Dear Brian,
Thanks for the help

Aha. I think I had misunderstood the syntax slightly, which explains why
I previously saw no debugging
