Detailed Description

template<typename PFuncInstanceType, typename ReduceExecutable, typename SpaceType>
struct pfunc::parallel_reduce< PFuncInstanceType, ReduceExecutable, SpaceType >

A function much akin to accumulate in STL. Takes in a range and a functor. The assumption is that the functor has the access to the entire container and hence all the harness needs to do is provide access to the correct range.

Parameters:

[in]	space	The iteration space. space is a model of Space concept.
[in]	func	The function object to be applied to every element. This function object has to take in an object of space_1D. i.e., void operator (const space_1D& space) { ... } must be defined on func. func is a model of ReduceExecutable concept.

NOTE: This function currently uses a local task manager.

NOTE: To use parallel_reduce, the Functor used in PFuncInstanceType must be pfunc::use_default! If a definite type is given, parallel_reduce fails to execute.

Constructor

Parameters:

[in]	space	The space over which to iterate
[in]	func	The function to execute over elements in this space
[in]	taskmgr	The task manager to use for this parallel_reduce

TODO: Make parallel_reduce work with global task manager.
