Hi, I don't think it would be a huge gain, if there is a gain at all. If we consider single processor multiple cores, the memory bandwidth is shared accross cores. Addition and substraction are meory bandwidth limited, so there would only be additional contention and thus less performance.Parallelization works best with far more computations than memory accesses.
