MPI_Win_sync

MPI_Win_sync, - Synchronize the private and public copies of the window

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Win_sync (MPI_Win win)

Fortran Syntax

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

Fortran 2008 Syntax

USE mpi_f08
MPI_Win_sync(win, ierror)
 TYPE(MPI_Win), INTENT(IN) :: win
 INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT PARAMETERS

  • win: Window object (handle).

OUTPUT PARAMETER

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

DESCRIPTION

MPI_Win_sync synchronizes the private and public window copies of win. For the purposes of synchronizing the private and public window, MPI_Win_sync has the effect of ending and reopening an access and exposure epoch on the window (note that it does not actually end an epoch or complete any pending MPI RMA operations).
