Energy-efficient design of real-time stream mining systems
Shaolei Ren, Cuiling Lan, Mihaela van der Schaar · 2013
In this paper, we propose an efficient solution for supporting real-time stream mining applications on heterogeneous systems operating at various processing speeds. Unlike the existing solutions that (1) rely on accurate knowledge or prediction of the service demand of each individual service request and (2) only consider a single type of delay constraint (e.g., typically, average or maximum delay), we propose an optimal algorithm, MinEnergy-MD, which determines the processing speeds for all classifiers based on the probability distribution of the service demand to minimize the average energy consumption while simultaneously satisfying multiple delay constraints. We conduct an extensive study to quantify the performance of MinEnergy-MD.
