[Mpi3-hybridpm] MPI_Comm_split_type

[Supalov, Alexander]

Thanks. The advice to implementers mentioned an Info argument (see 23/6). There appears to be no MPI_Info argument in the syntax (see 22/26). Is this a remnant of the ol'times, or a glint of the future?

Actually, having an MPI_Info here would be very tempting, as one could, e.g., ask the new communicator ranks to be reordered to honour cache hierarchy, or latency, etc. With the time we could then also agree on some keys/effects common to all implementations.

Folks,

Ron and I made some corrections to the MPI_Comm_split_type definition. 
Attached is a new version of the chapter with these changes.

Comments before the next telecon are welcome, so we can minimize the time we spend on this during the telecon.

Thanks,
