Detailed Description

OpenMP parallel implementation of the Map/reduce pattern.

Function Documentation

template<typename InputIt , typename Transformer , typename Result , typename Combiner >

Result grppi::map_reduce	(	parallel_execution_omp &	ex,
		InputIt	first,
		InputIt	last,
		Result	identity,
		Transformer &&	transform_op,
		Combiner &&	combine_op
	)

Invoke Map/reduce pattern on a data sequence with native parallel execution.

Template Parameters

InputIt	Iterator type used for input sequence.
Result	Result type of the reduction.
Transformer	Callable type for the transformation operation.
Combiner	Callable type for the combination operation of the reduction.

Parameters

ex	OpenMP parallel execution policy object.
first	Iterator to the first element in the input sequence.
last	Iterator to one past the end of the input sequence.
identity	Result value for the combination operation.
transf_op	Transformation operation.
combine_op	Combination operation.

Returns

Result of the map/reduce operation.
