Correction: Fortran is also covered.

Note that count size matter in particular is being addressed in another proposal that is currently C-centric. See MPI ticket #117, most likely targeted to MPI-3 now. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bill Long Sent: Thursday, May 28, 2009 7:34 PM To: MPI-3 Fortran working group Subject: Re: [MPI3 Fortran] Specify IN/OUT/INOUT in MPI spec?

That's fine - I was just doing this for a formatting example. I agree that different named constants for KIND values makes sense here. I'd take a lead from the C binding to see if it had different typedefs for the integer kinds.

I think the C binding could use some improvements first before following their lead. It is pretty out of date. For example...

Please, no! If we are going to use KIND, let it be done properly. There needs to be a set of KINDs, because you have at least three different uses of integers there.

I would tend to split them into counts (i.e. COUNT), handles (i.e. DATATYPE and COMM) and smallish integers (i.e. DEST, TAG and IERROR). But another division might be better.

I agree. The idea of using int for a buffer size is incompatible with arrays > 4GB. It should be size_t instead. Some sort of rework, along the lines Nick suggests, should be done for both the C and Fortran bindings. In the end they should match.
