Computing for the Environment
Environmental researchers rely on computers to expose the fundamental workings of our planet, to bring complicated questions to light, and to find solutions. By developing computational tools to model the Earth's evolution and climate, and invent new technologies, scientists in the Lawrence Berkeley National Laboratory's Computational Research, Earth Sciences, and Environmental Energy Technologies divisions are helping humanity adapt to a changing world.

This month, IEEE announced the ratification of the
IEEE P802.3az Energy-Efficient Ethernet standard, the first standard in the history of Ethernet to address proactive reduction in energy consumption for networked devices. Michael Bennett of Berkeley Lab’s IT Division is chair of the IEEE 802.3az Energy-Efficient Ethernet Task Force. Berkeley Lab CIO Rosio Alvarez and ESnet manager Steve Cotter also commented on the new standard. More>

A new Chinese supercomputer is poised to be the world's fastest. This week, Berkeley Lab Deputy Director Horst Simon, puts this event in context for the Wall Street Journal. Simon was the previous Associate Lab Director for Computing Sciences, a post now held by Kathy Yelick. More>
Astronomers have long relied on stellar explosions called Type Ia supernovae to measure the scale of the cosmos. But Dovi Poznanski of the Computational Reserach Division's Computational Cosmology Center believes that a second class of supernovae may now be put to the same use, providing an independent check on measurements that were first used more than a decade ago to discover the accelerating expansion of the Universe. His most recent findings were published on 1 October in the Astrophysical Journal and featured in an October 23 issue of Nature News. More>
Although the Green Flash research project has a lower profile these days than in 2008 when it was introduced, it still hasn’t been forgotten. In the October 14 article “For Proprietary HPC, Hope Springs Eternal,” HPCwire editor Michael Feldman surveys the landscape of specialized HPC systems and includes a paragraph on Green Flash, the specialized climate modeling system under development at Berkeley Lab.

Although jokes are often told about the physicist’s propensity for assuming everything is a sphere, they do this with good reason: more complex models are costly to simulate, in terms of computational resources. But, new research conducted on the National Energy Research Scientific Computing Center’s Cray XT4 Franklin system, using CASTRO, a program developed by Berkeley Lab's Ann Almgren and John Bell, have cracked the problem by using a new approach to create computer simulations of supernovae.
