MPI_File_write_all_end - Writes a file starting at the locations
specified by individual file pointers; ending part of a split collective
routine (blocking).
C Syntax
#include <mpi.h>
int MPI_File_write_all_end(MPI_File fh, const void *buf, MPI_Status *status)
USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_FILE_WRITE_ALL_END(FH, BUF, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, STATUS, IERROR
USE mpi_f08
MPI_File_write_all_end(fh, buf, status, ierror)
TYPE(MPI_File), INTENT(IN) :: fh
TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf
TYPE(MPI_Status) :: status
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
- fh
- File handle (handle).
- buf
- Initial
address of buffer (choice).
- status
- Status object (status).
- IERROR
- Fortran only: Error status (integer).
MPI_File_write_all_end
is the ending part of a split collective routine that stores the number
of elements actually written into the file associated with fh from the
user’s buffer buf in status. MPI_File_write_all_end blocks until the operation
initiated by MPI_File_write_all_begin completes. The data is written into
those parts of the file specified by the current view. All other fields
of status are undefined.
All the nonblocking collective routines for
data access are "split" into two routines, each with _begin or _end as
a suffix. These split collective routines are subject to the semantic rules
described in Section 9.4.5 of the MPI-2 standard.
Almost all MPI routines
return an error value; C routines as the value of the function and Fortran
routines in the last argument. C++ functions do not return errors. If the
default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error
the C++ exception mechanism will be used to throw an MPI::Exception object.
Before the error value is returned, the current MPI error handler is called.
For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN.
The error handler may be changed with MPI_File_set_errhandler; the predefined
error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal.
Note that MPI does not guarantee that an MPI program can continue past
an error.
