17.2.454. MPI_Win_set_info

MPI_Win_set_info - Set window info hints

17.2.454.1. SYNTAX

17.2.454.1.1. C Syntax

#include <mpi.h>

int MPI_Win_set_info(MPI_Win win, MPI_Info info)

17.2.454.1.2. Fortran Syntax

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

17.2.454.1.3. 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

17.2.454.2. INPUT PARAMETERS

  • win: Window on which to set info hints

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

17.2.454.3. OUTPUT PARAMETERS

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

17.2.454.4. DESCRIPTION

MPI_Win_set_info sets new values for the hints of the window associated with win. 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.

17.2.454.5. ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
