Scheduling on Power-Heterogeneous Processors [chapter]

Susanne Albers, Evripidis Bampis, Dimitrios Letsios, Giorgio Lucarelli, Richard Stotz
2016 Lecture Notes in Computer Science  
When a processor runs at speed s, then the rate with which the energy is consumed (i.e., the power) is f (s) with f a non-decreasing function of the speed.  ...  Standard Power Functions : Each processor p ∈ P satisfies the power function f p (s) = s αp , where α p > 1 is a small constant.
