Function Documentation

template<typename Identity , typename Combiner , typename Consumer , typename Generator >

void grppi::stream_reduce	(	parallel_execution_omp &	ex,
		int	window_size,
		int	offset,
		Identity	identity,
		Generator &&	generate_op,
		Combiner &&	combine_op,

	)

Invoke Stream reduction pattern on a stream with OpenMP parallel execution.

Template Parameters

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

Parameters

ex	OpenMP parallel 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.
generate_op	Generation operation.
combine_op	Combination operation.
consume_op	Consume operation.
