Detailed Description

template<typename Generator>
class stapl::skeletons::skeletons_impl::farm_pd< Generator >

This parametric dependency is used in farms skeleton to generate the initial seeds of computation.

This parametric dependency is similar to the zip parametric dependency, except it sends a farm_stub to the user-provided generator as well.

Example - the inputs to a spawned element created by this skeleton would be:

• farm_stub - which allows adding more work to the farm
• in<0>[idx]
• in<1>[idx]
• in<2>[idx]
• ...

Template Parameters

Op	the workfunction to be applied on each element
i	the number of input flows

Member Function Documentation

case_of()

template<typename Generator >

template<typename Coord , typename Visitor , typename In >

void stapl::skeletons::skeletons_impl::farm_pd< Generator >::case_of	(	Coord const &	,
		Coord const &	coord,
		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<typename Generator >

template<typename Size , typename Coord , typename FlowIndex >

std::size_t stapl::skeletons::skeletons_impl::farm_pd< Generator >::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
