¶virtual void fill_identity(void* dest,
size_t count) const
virtual void fill_identity(void* dest,
size_t count) constDescription
Fills count values starting at dest with the reduction's identity value. dest is considered uninitialized, operand size is implicit.
Parameters

const void* src,
size_t src_count) const
virtual void reduce(void* dest,
const void* src,
size_t src_count) constDescription
Reduces src_count values starting at src and stores the result in dest. Operand size is implicit.
Parameters
- void* dest
- const void* src
- size_t src_count
