.SH DESCRIPTION
|
|
.ft R
|
|
\fBMPI_Win_flush\fP completes all outstanding RMA operations initiated by the calling process to the target rank on the specified window. The operations are completed both at the origin and at the target. \fBMPI_Win_flush_all\fP completes all outstanding RMA operations to all targets.
|
|
.sp
|
|
Can only be called from within a passive target epoch.
|
|
|
|
.SH ERRORS
|
|
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
|
|
.sp
|
|
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 \fBMPI_Comm_set_errhandler\fP; 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.
