DESCRIPTION
-----------

:ref:`MPI_Win_complete` is a one-sided MPI communication synchronization call,
completing an RMA access epoch on *win* started by a call to
:ref:`MPI_Win_start`. :ref:`MPI_Win_complete` enforces the completion of preceding RMA
calls at the origin and not at the target. A put or accumulate call may
not have completed at the target when it has completed at the origin.
