MPI_WIN_FLUSH_LOCAL(RANK, WIN, IERROR)
INTEGER RANK, WIN, IERROR
MPI_WIN_FLUSH_LOCAL_ALL(IN, IERROR)
INTEGER WIN, IERROR
- rank
- Rank of window (nonnegative integer).
- win
- Window object
(handle).
- IERROR
- Fortran only: Error status (integer).
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.
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.
