I will file a proposal about this if there is a problem, but I wanted
to ask the group before I did so. In the changelog for MPI-2.1:
2. Section 3.2.2 on page 27, Section 16.1.6 on page 453, and Annex A.1
on page 491.
MPI_LONG_LONG_INT, MPI_LONG_LONG (as synonym), MPI_UNSIGNED_LONG_LONG,
MPI_SIGNED_CHAR, and MPI_WCHAR are moved from optional to official and
they
are therefore deï¬ned for all three language bindings.
Note that it says that these C datatype names must be in all three
language bindings.
Are C MPI datatypes supposed to be available in Fortran? I looked in
mpif.h for Open MPI, MPICH2, HP MPI, and Intel MPI, and I didn't see C
MPI datatypes in there (e.g., MPI_INT and MPI_FLOAT).
So:
- is there language somewhere in MPI that says that C datatypes are
not supposed to be in mpif.h? (and therefore the MPI-2.1 changelog is
wrong)
or
- are all 4 of the above MPI's wrong for not including the C datatypes
in mpif.h?
