Simulation Modeling for Speed Scaling Designs

This paper introduces an extensible simulation tool for the study of speed scaling designs for a single server with variable service rates. This simulator facilitates detailed performance analysis of scheduling and speed scaling policies under different background settings. Our component-based design separates the system configuration, like the power consumption model and the incoming workload, from the policy components for scheduling and speed scaling. Furthermore, the simulator allows for custom implementations of the data logger, so the instrumentation could be fine tuned to the desired level of detail for each run of the simulation. We present the design of the main components of our simulator. We then show example results to highlight the versatility of the simulator for studying different speed scaling configurations.
