NAME
MPI_File_write_ordered_end - Writes a file at a location specified by a shared file pointer; ending part of a split collective routine (blocking). SYNTAX
C Syntax #include <mpi.h> int MPI_File_write_ordered_end(MPI_File fh, void *buf, MPI_Status *status) Fortran Syntax INCLUDE 'mpif.h' MPI_FILE_WRITE_ORDERED_END(FH, BUF, STATUS, IERROR) <type> BUF(*) INTEGER FH, STATUS(MPI_STATUS_SIZE), IERROR C++ Syntax #include <mpi.h> void MPI::File::Write_ordered_end(const void* buf, MPI::Status& status) void MPI::File::Write_ordered_end(const void* buf) INPUT
/OUTPUT PARAMETER fh File handle (handle). INPUT PARAMETER
buf Initial address of buffer (choice). OUTPUT PARAMETERS
status Status object (status). IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_File_write_ordered_end is the ending part of a split collective routine that must be called by all processes in the communicator group associated with the file handle fh. MPI_File_write_ordered_end returns the number of elements written into the file associated with fh in status. NOTES
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. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func- tions 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. Open MPI 1.2 September 2006 MPI_File_write_ordered_end(3OpenMPI)

NAME
MPI_File_read_all_end - Reads a file starting at the locations specified by individual file pointers; ending part of a split collective routine (blocking). SYNTAX
C Syntax #include <mpi.h> int MPI_File_read_all_end(MPI_File fh, void *buf, MPI_Status *status) Fortran Syntax INCLUDE 'mpif.h' MPI_FILE_READ_ALL_END(FH, BUF, STATUS, IERROR) <type> BUF(*) INTEGER FH, STATUS(MPI_STATUS_SIZE), IERROR C++ Syntax #include <mpi.h> void MPI::File::Read_all_end(void* buf, MPI::Status& status) void MPI::File::Read_all_end(void* buf) INPUT
/OUTPUT PARAMETER fh File handle (handle). OUTPUT PARAMETERS
buf Initial address of buffer (choice). status Status object (status). IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_File_read_all_end is the ending part of a split collective operation that stores the number of elements actually read from the file associated with fh (at the current individual file pointer position maintained by the system) into the user's buffer buf in status. The data is taken out of those parts of the file specified by the current view. All other fields of status are undefined. NOTES
