Detailed Description

OpenMP parallel implementation of the Reduce pattern.

Function Documentation

template<typename InputIt , typename Identity , typename Combiner >

auto grppi::reduce	(	parallel_execution_omp &	ex,
		InputIt	first,
		InputIt	last,
		Identity	identity,
		Combiner &&	combine_op
	)

Invoke Reduce pattern with identity value on a data sequence with parallel OpenMP execution.

Template Parameters

InputIt	Iterator type used for input sequence.
Identity	Type for the identity value.
Combiner	Callable type for the combiner operation.

Parameters

ex	Parallel native 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	Identity value for the combiner operation.
combiner_op	Combiner operation for the reduction.
