NAME¶
MPI_Win_set_info - Set window info hints
C Syntax¶
#include <mpi.h>
int MPI_Win_set_info(MPI_Win win, MPI_Info info)
Fortran Syntax¶
INCLUDE 'mpif.h'
MPI_WIN_SET_INFO(WIN, INFO, IERROR)
INTEGER WIN, INFO, IERROR
- win
- Window on which to set info hints
- info
- Info object containing hints to be set on win
OUTPUT PARAMETERS¶
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION¶
MPI_WIN_SET_INFO sets new values for the hints of the window associated with
win. MPI_WIN_SET_INFO is a collective routine. The info object may be
different on each process, but any info entries that an implementation
requires to be the same on all processes must appear with the same value in
each process's info object.
ERRORS¶
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.
