User-Interaction-Based Energy Management

By Chris Gniady

Abstract: Improving energy efficiency is critical since future users will demand mobile devices with even longer battery life or higher performance and stationary systems that are cost effective to operate even when energy costs increase. The challenge that efficient energy management faces is matching the power state of the system resources to the application or user demand. The goal is to reduce energy consumption by keeping the device in the low-power state when not used, but at the same time provide high response when the demand for the device arrives. Current solutions are either not transparent and require programmer involvement, or are less effective in reducing energy consumption and can expose significant delays to the application and the user. The goal of the proposed work is to design a fully autonomous and unified system that will transparently examine and adapt to application demands of interactive applications in the current and future systems. This goal is achieved through highly detailed user and application behavior monitoring in the operating system. Capturing and understanding such user and application behavior is critical in meeting user demand for high performance while saving energy. The interaction based energy management had been successfully applied to disk, network interface, and CPU management.
