MPI_Win_flush_local, MPI_Win_flush_local_all - Complete all outstanding RMA operations at both the origin
#include <mpi.h> int MPI_Win_flush_local (int rank, MPI_Win win) int MPI_Win_flush_local_all (MPI_Win win)
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_WIN_FLUSH_LOCAL(RANK, WIN, IERROR) INTEGER RANK, WIN, IERROR MPI_WIN_FLUSH_LOCAL_ALL(WIN, IERROR) INTEGER WIN, IERROR
USE mpi_f08 MPI_Win_flush_local(rank, win, ierror) INTEGER, INTENT(IN) :: rank TYPE(MPI_Win), INTENT(IN) :: win INTEGER, OPTIONAL, INTENT(OUT) :: ierror MPI_Win_flush_local_all(win, ierror) TYPE(MPI_Win), INTENT(IN) :: win INTEGER, OPTIONAL, INTENT(OUT) :: 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.
