#1660 closed bug (invalid)

MPI_AINT incorrect size

Reported by: artem.v.yalozo@… Owned by: jayesh
Priority: major Milestone: future
Component: mpich Keywords:


There seems to be incorrect MPI_AINT definition in mpi.h for x64 architecture on Windows (4 bytes):
#define MPI_AINT ((MPI_Datatype)0x4c000443)

It should be (8 bytes):
#define MPI_AINT ((MPI_Datatype)0x4c000843)

The definition is incorrect as MPI_AINT is a pointer which size is given by:
#define MPID_Datatype_get_basic_size(a) (((a)&0x0000ff00)>>8)

There is no such issue on Linux.

Can you provide additional information on your issue (Which version of MPICH2 are you using? etc)?
I do not see the issue on an installation of MPICH2 1.4.1p1 x64 version on a test machine here.

The issue is relevant for the Intel MPI Library which uses winconfigure from MPICH2 1.4.1p1.
We will check if there is incorrect usage of the latter on our side.
