MPI_Win_flush_all − Complete all outstanding RMA operations at all targets
int MPI_Win_flush_all(MPI_Win win)
All RMA operations issued by the calling process to any target on the specified window prior to this call and in the specified window will have completed both at the origin and at the target when this call returns.
- window object (handle)
This routine is thread-safe. This means that this routine may be safely used by multiple threads without the need for any user-provided thread locks. However, the routine is not interrupt safe. Typically, this is due to the use of memory allocation routines such as malloc or other non-MPICH runtime routines that are themselves not interrupt-safe.
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
routines (except MPI_Wtime and MPI_Wtick )
return an error value; C routines as the value of the
function and Fortran routines in the last argument. Before
the value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job.
The error handler may be changed with
MPI_Comm_set_errhandler (for communicators),
MPI_File_set_errhandler (for files), and
MPI_Win_set_errhandler (for RMA windows). The MPI-1
routine MPI_Errhandler_set may be used but its use is
deprecated. The predefined error handler
MPI_ERRORS_RETURN may be used to cause error values
to be returned. Note that MPI does not guarentee that
an MPI program can continue past an error; however, MPI
implementations will attempt to continue whenever possible.
- No error; MPI routine completed successfully.
- Invalid source or destination rank. Ranks must be between zero and the size of the communicator minus one; ranks in a receive ( MPI_Recv , MPI_Irecv , MPI_Sendrecv , etc.) may also be MPI_ANY_SOURCE .
- Invalid MPI window object
- Other error; use MPI_Error_string to get more information about this error code.
