Hi Morten, Thanks, got it. Then another question,

Speaking of the engergy model, I am not sure why elaborate "imprecise" energy numbers do a better job than only a general statement: higher freq, more cap, and more power. Even for big.LITTLE systems, big and little CPUs also follow that statement respectively. Then it is just a matter of where to place tasks between them. Under such, the energy model might be useful, but still probably cpu_power_orig (from Vincent) might be enough.
