Welcome to the Synergy website

The Systems, Networking, and Energy Efficiency (Synergy) lab is at the CMU School of Computer Science, and is led by Yuvraj Agarwal. We are affiliated with the MESL lab at the UCSD Department of Computer Science and Engineering.

Our research focus is on designing networked systems that drive energy efficiency gains at all levels. Some of our core projects include the Energy Dashboard, which is a major effort in characterizing energy usage from the campus level down to the plug load level. SleepServers is another project of ours that seeks to reduce IT usage.

Contact Information

Our lab is located at 2113 in the CSE Building EBU3B. Our graduate student office is in 2150. Dr. Yuvraj Agarwal's office is at 2116. To get to the CSE Building, check out these directions.

Please contact any of the lab members or Virginia McIlwain (858-534-3047 or vmcilwain at cs.ucsd.edu) about visting us.

About Our Logo

Our logo consists of three hexagons, each repesenting a focus of our efforts. The top represents the hardware of our systems, the bottom represents the software that runs our systems, and the right represents that our systems are meant to make positive contributions to energy management and make the world a "greener" place. Thus our driving force is the synergy of these three.
