stapl::skeletons::skeletons_impl::do_while_pd< ContCond > Class Template Reference

A do_while parametric dependency represents an element in the dependence graph that controls if the next iteration of a do-while loop should be spawned or not. It does that by wrapping user's ContCond by do_while_stub with and sending memento_stack to it. More...

Detailed Description

template<typename ContCond>
class stapl::skeletons::skeletons_impl::do_while_pd< ContCond >

A do_while parametric dependency represents an element in the dependence graph that controls if the next iteration of a do-while loop should be spawned or not. It does that by wrapping user's ContCond by do_while_stub with and sending memento_stack to it.

Template Parameters

ContCond

a user provided continuation functor

template<typename ContCond >

template<typename Coord , typename Visitor , typename In >

void stapl::skeletons::skeletons_impl::do_while_pd< ContCond >::case_of	(	Coord const &	skeleton_size,
		Coord const &	coord,
		Visitor &	visitor,
		In &&	in_flow
	)		const

If coord is <i, h, ...> it wraps the WF with the following inputs and sends it to the visitor along with the m_op.

• in<0>[i]
• current memento_stack

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 WF 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 ContCond >

template<typename Size , typename Coord , typename FlowIndex >

std::size_t stapl::skeletons::skeletons_impl::do_while_pd< ContCond >::consumer_count	(	Size const &	,
		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
