Synopsis
MPI_Aint MPI_Aint_add(MPI_Aint base, MPI_Aint disp)Input Parameters
- base
-
base address (integer)
- disp
-
displacement (integer)
Notes
MPI_Aint_Add produces a new MPI_Aint value that is equivalent to the sum of the
base and disp arguments, where base represents a base address returned by a call
to MPI_GET_ADDRESS and disp represents a signed integer displacement. The resulting
address is valid only at the process that generated base, and it must correspond
to a location in the same object referenced by base. The addition is performed in
a manner that results in the correct MPI_Aint representation of the output address,
as if the process that originally produced base had called
MPI_Get_address((char *) base + disp, &result)Notes for Fortran
All MPI routines in Fortran (except for 'MPI_WTIME' and 'MPI_WTICK') have an additional argument 'ierr' at the end of the argument list. 'ierr' is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the 'call' statement.
All MPI objects (e.g., 'MPI_Datatype', 'MPI_Comm') are of type 'INTEGER' in Fortran.
