 Energy and power are increasingly becoming critical challenges in the design of future computing systems. The SmartPower project at hp labs seeks to address these challenges through holistic solutions, across multiple levels of the system, and optimized for the overall end-user experience. In this talk, I will motivate the power management challenge and present a systematic taxonomy of inefficiencies that lead to overconsumption of power. I will then present results from four major projects that address these inefficiencies - energy-aware user interfaces, heterogeneity-based architectures, ensemble-level power control, and integrated IT/facilities resource provisioning. Though these approaches straddle different market segments and different levels of the system, they all achieve dramatic improvements, with factors of two to twenty reductions in the power consumption. I will conclude with a discussion of some of the toolsets developed as part of this project and ongoing and future work.

Speaker Bio
Partha Ranganathan is currently a principal research scientist at Hewlett Packard Labs. His research interests are in computer architecture and parallel processing with a focus on performance, power, manageability, and evaluation.
 He currently leads the SmartPower program at HP Labs, designing power-efficient solutions across the entire computing continuum. Partha's past research has focused on application-optimized architecture design, and performance, programmability, and simulation of multiprocessing systems.

Partha received his B.Tech degree from the Indian Institute of Technology, Madras and his M.S. and Ph.D. from Rice University, Houston. He was a primary developer of the publicly distributed Rice Simulator for ILP Multiprocessors (RSIM), and is a recipient of the Lodieska Stockbridge Vaughan fellowship and an IIT Madras Alumni Award.
