This is the interface for the bitmap utilities provided by StarPU.
struct starpu_bitmap* starpu_bitmap_create | ( | void | ) |
create a empty starpu_bitmap
void starpu_bitmap_destroy | ( | struct starpu_bitmap * | b | ) |
free b
void starpu_bitmap_set | ( | struct starpu_bitmap * | b, |
int | e | ||
) |
set bit e
in b
void starpu_bitmap_unset | ( | struct starpu_bitmap * | b, |
int | e | ||
) |
unset bit e
in b
void starpu_bitmap_unset_all | ( | struct starpu_bitmap * | b | ) |
unset all bits in b
int starpu_bitmap_get | ( | struct starpu_bitmap * | b, |
int | e | ||
) |
return true iff bit e
is set in b
void starpu_bitmap_unset_and | ( | struct starpu_bitmap * | a, |
struct starpu_bitmap * | b, | ||
struct starpu_bitmap * | c | ||
) |
Basically compute starpu_bitmap_unset_all
(a
) ; a
= b
& c
;
void starpu_bitmap_or | ( | struct starpu_bitmap * | a, |
struct starpu_bitmap * | b | ||
) |
Basically compute a
|= b
int starpu_bitmap_and_get | ( | struct starpu_bitmap * | b1, |
struct starpu_bitmap * | b2, | ||
int | e | ||
) |
return 1 iff e
is set in b1
AND e
is set in b2
int starpu_bitmap_cardinal | ( | struct starpu_bitmap * | b | ) |
return the number of set bits in b
int starpu_bitmap_first | ( | struct starpu_bitmap * | b | ) |
return the index of the first set bit of b
, -1 if none
int starpu_bitmap_last | ( | struct starpu_bitmap * | b | ) |
return the position of the last set bit of b
, -1 if none
int starpu_bitmap_next | ( | struct starpu_bitmap * | b, |
int | e | ||
) |
return the position of set bit right after e
in b
, -1 if none
int starpu_bitmap_has_next | ( | struct starpu_bitmap * | b, |
int | e | ||
) |
