The new functions for caching on windows are:
MPI_WIN_CREATE_KEYVAL(win_copy_attr_fn, win_delete_attr_fn, win_keyval, extra_state) | |
IN win_copy_attr_fn | copy callback function for win_keyval (function) |
IN win_delete_attr_fn | delete callback function for win_keyval (function) |
OUT win_keyval | key value for future access (integer) |
IN extra_state | extra state for callback functions |
int MPI_Win_create_keyval(MPI_Win_copy_attr_function *win_copy_attr_fn, MPI_Win_delete_attr_function *win_delete_attr_fn, int *win_keyval, void *extra_state)
MPI_WIN_CREATE_KEYVAL(WIN_COPY_ATTR_FN, WIN_DELETE_ATTR_FN, WIN_KEYVAL, EXTRA_STATE, IERROR)

) }
The argument win_copy_attr_fn may be specified as
MPI_WIN_NULL_COPY_FN or
MPI_WIN_DUP_FN
from either C, C++, or Fortran.
MPI_WIN_NULL_COPY_FN
is a function that does nothing other than returning flag = 0
and MPI_SUCCESS.
MPI_WIN_DUP_FN is a simple-minded
copy function that sets flag = 1,
returns the value of
attribute_val_in in attribute_val_out, and
returns MPI_SUCCESS.
The argument win_delete_attr_fn may be specified as
MPI_WIN_NULL_DELETE_FN from either C, C++, or Fortran.
MPI_WIN_NULL_DELETE_FN is a function that does nothing, other
than returning MPI_SUCCESS.
The C callback functions are:
typedef int MPI_Win_copy_attr_function(MPI_Win oldwin, int win_keyval, void *extra_state, void *attribute_val_in, void *attribute_val_out, int *flag);
and
typedef int MPI_Win_delete_attr_function(MPI_Win win, int win_keyval, void *attribute_val, void *extra_state);
The Fortran callback functions are:
SUBROUTINE WIN_COPY_ATTR_FN(OLDWIN, WIN_KEYVAL, EXTRA_STATE, ATTRIBUTE_VAL_IN, ATTRIBUTE_VAL_OUT, FLAG, IERROR)
and
SUBROUTINE WIN_DELETE_ATTR_FN(WIN, WIN_KEYVAL, ATTRIBUTE_VAL, EXTRA_STATE, IERROR)
The C++ callbacks are:
{ typedef int MPI::Win::Copy_attr_function(const MPI::Win& oldwin, int win_keyval, void* extra_state, void* attribute_val_in, void* attribute_val_out, bool& flag); (binding deprecated, see Section Deprecated since MPI-2.2
) }
and
{ typedef int MPI::Win::Delete_attr_function(MPI::Win& win, int win_keyval, void* attribute_val, void* extra_state); (binding deprecated, see Section Deprecated since MPI-2.2
) }
int MPI_Win_free_keyval(int *win_keyval)
MPI_WIN_FREE_KEYVAL(WIN_KEYVAL, IERROR)
{ static void MPI::Win::Free_keyval(int& win_keyval) (binding deprecated, see Section Deprecated since MPI-2.2
) }
int MPI_Win_set_attr(MPI_Win win, int win_keyval, void *attribute_val)
MPI_WIN_SET_ATTR(WIN, WIN_KEYVAL, ATTRIBUTE_VAL, IERROR)
{ void MPI::Win::Set_attr(int win_keyval, const void* attribute_val) (binding deprecated, see Section Deprecated since MPI-2.2
) }
int MPI_Win_get_attr(MPI_Win win, int win_keyval, void *attribute_val, int *flag)
MPI_WIN_GET_ATTR(WIN, WIN_KEYVAL, ATTRIBUTE_VAL, FLAG, IERROR)
{ bool MPI::Win::Get_attr(int win_keyval, void* attribute_val) const (binding deprecated, see Section Deprecated since MPI-2.2
) }
int MPI_Win_delete_attr(MPI_Win win, int win_keyval)
MPI_WIN_DELETE_ATTR(WIN, WIN_KEYVAL, IERROR)
{ void MPI::Win::Delete_attr(int win_keyval) (binding deprecated, see Section Deprecated since MPI-2.2
) }

If an attribute copy function or attribute delete function returns other than
MPI_SUCCESS, then the call that caused it to be invoked (for example,
MPI_WIN_FREE), is erroneous.
MPI_WIN_FREE_KEYVAL(win_keyval) INOUT win_keyval key value (integer)

MPI_WIN_SET_ATTR(win, win_keyval, attribute_val) INOUT win window to which attribute will be attached (handle) IN win_keyval key value (integer) IN attribute_val attribute value

false OUT flag false if no attribute is associated with
the key (logical)
