LEADERSHIP IN ENERGY EFFICIENT COMPUTING
Lawrence Berkeley National Laboratory is an internationally recognized leader in power-efficient computing. Scientists and engineers in Berkeley Lab's Computational Research, National Energy Research Scientific Computing, Information Technology, and Environmental Energy Technologies divisions are working together to solve a significant problem faced by computing centers worldwide: how to engineer, build and operate power-efficient computers and data centers. Their research examines a wide range of issues, from creating new computer architectures using low-power processors to innovative building designs.
FEATURE STORY
Green Computing Exploring energy-efficient computing, from system designs to applications.
RESEARCH
The Greening of HPC Will power consumption become the limiting factor for future growth in high performance computing (HPC)? View the webcast of a lecture by Berkeley Lab's Associate Laboratory Director for Computing Sciences, Horst Simon.
Green Flash In collaboration with the chip engineering firm Tensilica, Inc., Berkeley Lab's Green Flash project is exploring more power-efficient alternatives to conventional supercomputers that are built with general-purpose processors. Supercomputers built with embedded chips — used to run cell phones and other portable gadgets — could be the low-power and less expensive alternatives for certain types of research such as climate modeling.
Data Centers Bill Tschudi, Dale Sartor and Rich Brown from Berkeley Lab's Environmental Energy Technologies Division (EETD) lead projects that study ways to assess energy efficiency in data centers and develop strategies and technologies to reduce their power consumption.

NERSC Read the report by Shoaib Kamil and John Shalf on gauging the power efficiency of the new flagship supercomputer at the National Energy Research Scientific Computing (NERSC) center.
TOP500 Researchers are raising awareness about the need to collect power consumption data and promote energy efficient designs for supercomputers. This initiative is underway at TOP500, the semi-annual ranking of the world's fastest supercomputers.
Digital Networks Berkeley Lab is working with the electronics industry and standard-setting organizations to reduce energy use of electronic equipment through networking. Topics range from physical interfaces (e.g. Ethernet) to protocols for information technology and consumer electronics devices. The collaboration would lead to energy savings in homes, offices and data centers. Berkeley Lab also performs technical research for the EPA Energy Star program. Researchers who are leading the work include Rich Brown, Bruce Nordman from EETD and Mike Bennett from IT.
