Detailed Description

Interface for applying the Stream reduction pattern.

Function Documentation

template<typename Execution , typename Identity , typename Combiner >

auto grppi::stream_reduce	(	Execution &	ex,
		int	window_size,
		int	offset,
		Identity	identity,
		Combiner &&	combine_op
	)

Invoke Stream reduction pattern on a stream that can be composed in other streaming patterns.

Template Parameters

Identity	Type of the identity value used by the combiner.
Combiner	Callable type used for data items combination.

Parameters

ex	Sequential execution policy object.
window_size	Number of consecutive items to be reduced.
offset	Number of items after of which a new reduction is started.
identity	Identity value for the combination.
combine_op	Combination operation.
