MPI_Win_set_info - Set window info hints
#include <mpi.h>
int MPI_Win_set_info(MPI_Win win, MPI_Info info)
USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_WIN_SET_INFO(WIN, INFO, IERROR)
INTEGER WIN, INFO, IERROR
USE mpi_f08
MPI_Win_set_info(win, info, ierror)
TYPE(MPI_Win), INTENT(IN) :: win
TYPE(MPI_Info), INTENT(IN) :: info
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
- win
- Window on which to set info hints
- info
- Info object
containing hints to be set on win
- IERROR
- Fortran only:
Error status (integer).
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.
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.
