[Mpi3-hybridpm] Telecon 10/6 at 12pm central

[James Dinan]

As I've written it, the result would be an implementation-defined 
default neighborhood.  I think it's challenging to get more specific 
than this.

We could include an advice to implementers to the effect that this 
split_type should return a communicator in which processes can 
communicate efficiently with one another.
