Detailed Description

template<typename Op, typename Tag>
class stapl::skeletons::skeletons_impl::binomial_tree_pd< Op, Tag >

This reduce parametric dependency is one of the several possible parametric dependencies that can be used in reduction.

This parametric dependency is used with tree in order to create reduction trees. Other possible choices for reduction dependence skeletons are right_binomial_tree_pd and left_binomial_tree_pd.

Template Parameters

Op	the workfunction to be applied on each pair of elements
Tag	determines the type of the reduce parametric dependency

◆ consumer_count()

template<typename Op , typename Tag >

template<typename Size , typename Coord , typename FlowIndex >

std::size_t stapl::skeletons::skeletons_impl::binomial_tree_pd< Op, Tag >::consumer_count	(	Size const &	skeleton_size,
		Coord const &	producer_coord,
		FlowIndex	flow_index
	)		const

determines how many of the instances of this parametric dependency will be consuming from a producer with a given coordinate. This is a reverse query as compared to case_of.

Template Parameters

FlowIndex the flow index to which this request is sent
