Member Function Documentation

case_of()

template<typename Coord , typename Visitor , typename In >

void stapl::skeletons::skeletons_impl::bitreversal_pd::case_of	(	Coord const &	skeleton_size,
		Coord const &	coord,
		Visitor &	visitor,
		In &&	in_flow
	)		const

If coord is <i, h, ...> it wraps the identity op with the following inputs and sends it to the visitor.

• in<0>[bitreversal_index(i)]

Parameters

skeleton_size	<n, m, p, ...> where each element is potentially multi-dimensional.
coord	<i, j, k, ...> where i < n, j < m, k < p
visitor	the information about Op and input is passed so that later this information can be converted to a node in the dependence graph
in_flow	a tuple of input flows to consume from

consumer_count()

template<typename Size , typename Coord , typename FlowIndex >

std::size_t stapl::skeletons::skeletons_impl::bitreversal_pd::consumer_count	(	Size const &	skeleton_size,
		Coord const &	,
		FlowIndex
	)		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
