Abstract
Power and energy constraints are now the driving force in all device markets from the cloud to desktop to mobile. To deliver energy efficiency however requires both hardware and software innovations, and in particular, vastly more capable system software (compiler, runtime, OS) together with new programming models. This requirement comes in part from the challenge of optimizing power and performance together, which is substantially more difficult than managing performance alone. This talk presents quantitative power, performance, and energy measurements on a range of workloads and devices, from server class machines to mobile. We show how a managed runtime can exploit differentiated workload characteristics to significantly improve energy efficiency. Our results suggest that software must play a larger role in order to achieve energy efficiency in future systems.
