Hi, openmpi developers.
I'd like to report that MPI_STATUS_SIZE in mpif-config.h of openmpi-1.6.2 compiled with -i8 fortran option(Fort integer size: 8) is defined as 3, which is half of normal opnempi's MPI_STATUS_SIZE. I think this also should be 6. openmpi(Fort integer size: 8) ! ! Miscellaneous constants ! integer MPI_STATUS_SIZE parameter (MPI_STATUS_SIZE=3) openmpi(Fort integer size: 4) ! ! Miscellaneous constants ! integer MPI_STATUS_SIZE parameter (MPI_STATUS_SIZE=6) Best regards, Tetsuya Mishima
