Detailed Description

template<typename real, class RDC>
class vex::Reductor< real, RDC >

Parallel reduction of arbitrary expression.

Reduction uses small temporary buffer on each device present in the queue parameter. One Reductor class for each reduction kind is enough per thread of execution.

Compute reduction of the input expression.

The input expression may be as simple as a single vector, although expressions of arbitrary complexity may be reduced.
