[Mpi-22] #117: Define a new MPI_Count Datatype

[Supalov, Alexander]

Yes. The #define and typedef ways can complement each other. The #define way will actually not change anything once the preprocessor is run - ints will literally be ints, etc. This would be the mildest way of introducing MPI_Count into the code. The typedef will make the code look different, at least syntactically. If it's set to int, it will be almost, but not quite like #define. It it's set to long,it will be what we want to have for 64-bit ints (provided we want signed counts, that is).

By the way, has this signed vs unsigned been discussed in this context?

The current proposal has a typedef instead of #define. Are there any specific reasons for preferring the pre-processor macro approach? 

Thanx!

Hi,

Thanks. I added an offline comment regarding the #define trick for MPI-2.2. Has this been addressed?

Best regards.

I've updated Ticket #117 ( Define a new MPI_Count Datatype ) to address the issues raised at the MPI Forum Meeting. Is there any other concern that is not addressed in this ticket?

Thanx!
Kannan
