Detailed Description

template<typename ReduceType, typename Float2, typename FloatN>
struct quda::blas::axpyCGNorm2< ReduceType, Float2, FloatN >

Specialized kernel for the modified CG norm computation for computing beta. Computes y = y + a*x and returns norm(y) and dot(y, delta(y)) where delta(y) is the difference between the input and out y vector.
