NAME

       MPI_Win_flush_local, MPI_Win_flush_local_all - Complete all outstanding RMA operations at both the origin

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Win_flush_local (int rank, MPI_Win win)

       int MPI_Win_flush_local_all (MPI_Win win)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_WIN_FLUSH_LOCAL(RANK, WIN, IERROR)
            INTEGER RANK, WIN, IERROR

       MPI_WIN_FLUSH_LOCAL_ALL(IN, IERROR)
            INTEGER WIN, IERROR

INPUT PARAMETERS

       rank      Rank of window (nonnegative integer).

       win       Window object (handle).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Win_flush_local  locally  completes  at  the  origin  all outstanding RMA operations initiated by the
       calling process to the target process specified by rank on the specified window. For example, after  this
       routine  completes,  the  user  may  reuse  any  buffers  provided to put, get, or accumulate operations.
       MPI_Win_flush_local_all locally completes at the origin all outstanding RMA operations to all targets.

       Can only be called from within a passive target epoch.

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.
