SYNTAX

C Syntax

#include <mpi.h>
int MPI_Win_sync (MPI_Win win)

Fortran Syntax

INCLUDE ’mpif.h’
MPI_WIN_SYNC(WIN, IERROR)
        INTEGER WIN, 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).

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.
