Thus to s= ave energy you want your task to be computed ASAP - so that it can be in lo= w frequency mode for as long as possible. Turns out it is the best power sa= ving optimization. And as counterintuitive as it is - it is most important = for big data centers (less power used =3D> less heat waste =3D> less coolin= g needed)
