[Mpi3-abi] Meeting notes from 10th March

[Jeff Brown]

I propose a way we can make progress ...

Let's start populating a matrix (excel spreadsheet) with a column for 
each MPI implementation, and rows for the various MPI datatypes, 
constants, etc. where the internal implementations varys.  I'll kick 
it off for OpenMPI and send out.

The last column of the matrix can be "ABI" where we propose a common 
approach across the implementations.

A couple of driving principles:
1. the ABI solution shouldn't negatively impact quality of implementation
2. minimize platform specific solutions

I'd like to see if we can produce a single ABI that spans platforms.

comments?
