Detailed Description

Functions for performing parallel for_each over iterables. This intends to more-or-less mimic std::for_each, with a possible (Concurrent)TaskSet passed in for external wait capability, and ForEachOptions for controlling the wait behavior and limiting of parallelism.

Function Documentation

for_each() [1/2]

template<typename Iter , typename F >

void dispenso::for_each	(	Iter	start,
		Iter	end,
		F &&	f,
		ForEachOptions	options = {}
	)

A function like std::for_each, but where the function is invoked in parallel across the passed range.

Parameters

start	The iterator for the start of the range.
end	The iterator for the end of the range.
f	The function to execute in parallel. This is a unary function that must be capable of taking dereference of Iter.
options	See ForEachOptions for details; however it should be noted that this function must always wait, and therefore options.wait is ignored.

for_each() [2/2]

template<typename TaskSetT , typename Iter , typename F >

void dispenso::for_each	(	TaskSetT &	tasks,
		Iter	start,
		Iter	end,
		F &&	f,
		ForEachOptions	options = {}
	)

A function like std::for_each, but where the function is invoked in parallel across the passed range.

Parameters

tasks	The task set to schedule the for_each on.
start	The iterator for the start of the range.
end	The iterator for the end of the range.
f	The function to execute in parallel. This is a unary function that must be capable of taking dereference of Iter.
options	See ForEachOptions for details.

for_each_n() [1/2]

template<typename Iter , typename F >

void dispenso::for_each_n	(	Iter	start,
		size_t	n,
		F &&	f,
		ForEachOptions	options = {}
	)

A function like std::for_each_n, but where the function is invoked in parallel across the passed range.

Parameters

start	The iterator for the start of the range.
n	The length of the range.
f	The function to execute in parallel. This is a unary function that must be capable of taking dereference of Iter.
options	See ForEachOptions for details; however it should be noted that this function must always wait, and therefore options.wait is ignored.

for_each_n() [2/2]

template<typename TaskSetT , typename Iter , typename F >

void dispenso::for_each_n	(	TaskSetT &	tasks,
		Iter	start,
		size_t	n,
		F &&	f,
		ForEachOptions	options = {}
	)

A function like std::for_each_n, but where the function is invoked in parallel across the passed range.

Parameters

tasks	The task set to schedule the for_each on.
start	The iterator for the start of the range.
n	The length of the range.
f	The function to execute in parallel. This is a unary function that must be capable of taking dereference of Iter.
options	See ForEachOptions for details.
