Modeling the Power Variability of Core Speed Scaling on Homogeneous Multicore Systems

Figure 2

Theoretical Pareto frontier (in red) suggested by our model. From any user specified point , following the vertical line (), we can reach point which can provide the same average speed with the lowest power. The power difference between and is the saved power. Following the horizontal line (), we can reach point which can provide the highest throughput (the fastest average speed) with the same power. The speed difference between and is the increased average speed. Following line (), we can reach point which can provide higher speed with less power than .
