26. Addresses


Up: Data Types Next: File Offsets Previous: Choice

Some MPI procedures use address arguments that represent an absolute address in the calling program. The datatype of such an argument is MPI_Aint in C, MPI::Aint in C++ and INTEGER (KIND= MPI_ADDRESS_KIND) in Fortran. These types must have the same width and encode address values in the same manner such that address values in one language may be passed directly to another language without conversion. There is the MPI constant MPI_BOTTOM to indicate the start of the address range.
