Detailed Description

template<std::size_t Arity, typename Op, typename Span, bool SetResult>
class stapl::skeletons::skeletons_impl::pre_broadcast_pd< Arity, Op, Span, SetResult >

Creates a set_result parametric dependency given a op. Basically this parametric dependency is only used for sinking values of skeletons which couldn't currently set their results directly without using sink_value skeleton.

Template Parameters

Arity	the arity of set_result
Op	the workfunction to be used in each set_result parametric dependency
Span	the span for the previous skeleton that is passed to set result for detecting if the corresponding task is spanned or not
SetResult	whether put the task result on the result container or not

Member Function Documentation

case_of()

template<std::size_t Arity, typename Op , typename Span , bool SetResult>

template<typename Coord , typename Visitor , typename In >

void stapl::skeletons::skeletons_impl::pre_broadcast_pd< Arity, Op, Span, SetResult >::case_of	(	Coord const &	skeleton_size,
		Coord const &	,
		Visitor &	visitor,
		In &&	in_flow
	)		const

If coord is <idx, ...> it wraps the Op with the following inputs and sends it to the visitor along with the m_op.

• in<0>[idx]
• in<1>[idx]
• ...

Parameters

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<std::size_t Arity, typename Op , typename Span , bool SetResult>

template<typename Size , typename Coord , typename FlowIndex >

std::size_t stapl::skeletons::skeletons_impl::pre_broadcast_pd< Arity, Op, Span, SetResult >::consumer_count	(	Size const &	skeleton_size,
		Coord const &	coord,
		FlowIndex const &
	)		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

Parameters

skeleton_size	the size of skeleton dimension
coord	the producer coordination

Template Parameters

FlowIndex

the flow index to which this request is sent
