MPI_Win_set_info

:ref:`MPI_Win_set_info` - Set window info hints

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Win_set_info(MPI_Win win, MPI_Info info)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_WIN_SET_INFO(WIN, INFO, IERROR)
     INTEGER WIN, INFO, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Win_set_info(win, info, ierror)
     TYPE(MPI_Win), INTENT(IN) :: win
     TYPE(MPI_Info), INTENT(IN) :: info
     INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT PARAMETERS

  • win: Window on which to set info hints
  • info: Info object containing hints to be set on win

OUTPUT PARAMETERS

  • ierror: Fortran only: Error status (integer).

DESCRIPTION

:ref:`MPI_WIN_SET_INFO` sets new values for the hints of the window associated with win. :ref:`MPI_WIN_SET_INFO` is a collective routine. The info object may be different on each process, but any info entries that an implementation requires to be the same on all processes must appear with the same value in each process's info object.
