Area: energy efficiency
Energy-efficient operation of distributed systems has been receiving increased attention, in both wireless/mobile systems (prolonged battery life times) and cluster systems (reduced costs for operation and cooling and increased reliability). This research focuses on the resource-efficient operation of such systems, applying technologies and solutions such as low-power sleep modes, frequency scaling, or application-specific transcoding of information, while at the same time satisfying applications' needs for performance, Quality-of-Service, and timeliness. Further, in distributed systems, devices typically are selfish in the sense that they manage their own resources without considering the consequences for resources and applications on remote devices. Therefore, this research is developing resource management solutions that enable the efficient integration of multiple constraints, resources, and devices. The new approach, dubbed judicious resource management, moves away from traditional, isolated resource management solutions and focuses on the prevention of unanticipated side effects of interdependent resource adaptations.
