NAME¶
MPI_Win_sync, - Synchronize the private and public copies of the window
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
- 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.
