MPI_Win_sync function

Synchronizes the private and public window copies of win.

Syntax

int MPIAPI MPI_Win_sync(
  _Inout_ MPI_Win *win
);

Parameters

• win [in]
  Window object.

Return value

Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.

In Fortran, the return value is stored in the IERROR parameter.

Fortran

    MPI_WIN_SYNC(WIN, IERROR)
        INTEGER WIN, IERROR

Remarks

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).

Microsoft MPI uses unified memory model, and so doesn't utilize private and public copies of the window memory.
