Detailed Description

template<typename Functor>
struct internal::VectorOperations::TBBForFunctor< Functor >

This struct takes the loop range from the tbb parallel for loop and translates it to the actual ranges of the for loop within the vector. It encodes the grain size but might choose larger values of chunks than the minimum grain size. The minimum grain size given to tbb is then simple

1. For affinity reasons, the layout in this loop must be kept in sync with the respective class for reductions further down.
