man MPI_Address (Fonctions bibliothèques) - Gets the address of a location in memory

NAME

MPI_Address - Gets the address of a location in memory

SYNOPSIS

#include "mpi.h"
int MPI_Address( void *location, MPI_Aint *address)

INPUT PARAMETERS

location
- location in caller memory (choice)

OUTPUT PARAMETER

address
- address of location (integer)

NOTE

This routine is provided for both the Fortran and C programmers. On many systems, the address returned by this routine will be the same as produced by the C & operator, but this is not required in C and may not be true of systems with word- rather than byte-oriented instructions or systems with segmented address spaces.

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.
