Classes
struct	stapl::map_factory< WF, b_coarse, SchedInfo >
	Factory that generates the tasks needed for a map operation. A map operation applies the work function provided on each set of elements of the input views that have the same offset from the beginning of their respective view. More...
struct	stapl::map_reduce_factory< MapWF, ReduceWF, b_coarse >
	Factory that generates the tasks needed for a map reduce operation. A map reduce operation applies the map work function provided on each set of elements of the input views that have the same offset from the beginning of their respective view. The map operations return values that are combined using the reduce operation provided to form a single result value. The result value is returned to each location in the gang executing the map_reduce call. More...
struct	stapl::prototype::result_of::map_reduce< Map, Reduce, b_coarse, >
	Computes the result type of a map_reduce PARAGRAPH. More...
class	stapl::composition::coarse_map_wf< MapWF >
	The default coarsened workfunction uses iterators to apply the elementary workfunction to each element in coarsened view passed to it. More...
struct	stapl::composition::map_factory< MapWF, b_coarse >
	Factory implementing functional version of map_func which returns a view over the result of the mapping function applied to all elements. The input views are not mutated. More...
struct	stapl::composition::result_of::map_func< MapWF, >
	Reflect return type of map_func passed workfunction MapWF and a variable number of views. More...
struct	stapl::composition::nest_map_mr_factory
	Customized implementation of a map_func(map_reduce()...) skeleton that is used for matrix vector multiplication. More...
class	stapl::detail::counter_based_terminator
	Custom PARAGRAPH termination detection which signals termination after a predefined number of invocations of the receive_notify method. More...
struct	stapl::composition::result_of::map_func< prototype::functional::inner_product, V0, V1 >
	Reflect return type of map_func specialization when workfunction is prototype::functional::inner_product. More...
struct	stapl::composition::result_of::map_func< binder2nd< Operation, Stored, false >, V0 >
	Reflect return type of map_func specialization when unary workfunction is an instantiation of the binder2nd class template. More...
struct	stapl::composition::result_of::map_func< binder1st< Operation, Stored, true >, V0 >

Detailed Description

The existing hand-written factories used prior to the existence of the Skeleton Framework.

The explicit factories are the previous approach of expressing parallel algorithms. Most of the explicit factories are now replaced by their skeleton-based equivalent. A few remaining uses are used for testing purposes and will be removed as soon as their equivalent is implemented in the Skeletons Framework.

Function Documentation

map_func() [1/3]

template<typename V0 , typename V1 >

result_of::map_func< prototype::functional::inner_product, V0, V1>::type stapl::composition::map_func	(	prototype::functional::inner_product const &	wf,
		V0 const &	v0,
		V1 const &	v1
	)

Signature of function template map_func that matches cases when the workfunction is prototype::functional::inner_product.

Specializes the implementation for this case, creating a PARAGRAPH using the nest_map_mr_factory factory.

Parameters

wf	An instance of the prototype::functional::inner_product with initialized elementary operations.
v0	A one dimensional view input.
v1	A one dimensional view input.

Returns

A view of the results of the spawned PARAGRAPH computation.

map_func() [2/3]

template<typename Operation , typename Stored , typename V0 >

result_of::map_func<binder2nd<Operation, Stored, false>, V0>::type stapl::composition::map_func	(	binder2nd< Operation, Stored, false > const &	wf,
		V0 const &	v0
	)

Converts map_func call with stapl::binder2nd as the workfunction to one with the base workfunction of type Operation and a repeat_view in place of the bound view of type Stored.

A replicated view and a view bound to a workfunction with a bind operation are equivalent. Normalize to a common form that makes the PARAGRAPH aware of all views.

map_func() [3/3]

template<typename Operation , typename Stored , typename V0 >

result_of::map_func<binder1st<Operation, Stored, true>, V0>::type stapl::composition::map_func	(	binder1st< Operation, Stored, true > const &	wf,
		V0 const &	v0
	)

Converts map_func call with stapl::binder1st as the workfunction to one with the base workfunction of type Operation and a repeat_view in place of the bound view of type Stored.

A replicated view and a view bound to a workfunction with a bind operation are equivalent. Normalize to a common form that makes the PARAGRAPH aware of all views.
