class reducer { /* full declaration omitted */ };

Description

Type-erased runtime reduction operation. Used to prepare and complete reductions on host memory in the executor.

Declared at: include/reduction.h:13

• ~reducer() → virtual
• operator=(const reducer &) → reducer &
• operator=(reducer &&) → reducer &
• reducer()
• reducer(const reducer &)
• reducer(reducer &&)

¶virtual void fill_identity(void* dest,
                           size_t count) const

Description

Fills count values starting at dest with the reduction's identity value. dest is considered uninitialized, operand size is implicit.

Declared at: include/reduction.h:21

Parameters

void* dest

size_t count

Description

Reduces src_count values starting at src and stores the result in dest. Operand size is implicit.

Declared at: include/reduction.h:18
