Scalable computing system, power management, energy efficiency


The authors propose a controlled model specifically designed for dynamic allocation of resources to reach the scalable relationship between the energy efficiency and the performance of a computing system. In their system, they use the power manager to control every resource in the system according to the operating characteristic information from hardware, software, and users. They also present an effective power policy for optimal energy usage. The power manager can select a different number of resources for performing the various applications according to the energy-optimal allocation formulation. In addition, simulation on a simple application with a certain set of parameters of the 89C51 multiprocessor system shows that the proposed method can save about 28%–50% of energy consumption.
