Planck Mission Delivers First All-Sky Image
“An extraordinary treasure chest of new data for astronomers, from the closest portions of the Milky Way to the furthest reaches of space and time,” says the European Space Agency of the Planck mission’s first all-sky image. The satellite was launched in May 2009 and has been surveying the sky since August 2009. NERSC hosts the U.S. Planck team’s data analysis through the Computational Cosmology Center, a collaboration of the Computational Research and Physics Divisions, with a group including Julian Borrill, Christopher Cantalupo, Ted Kisner, and Radek Stompor. George Smoot co-authored the proposal that led to Planck and, with Martin White of Physics, is a Planck scientist. Read more about Planck’s Berkeley Lab roots.
SciDAC 2010 Conference and Tutorials This Week
Each year, scientists participating in the Scientific Discovery through Advanced Computing Program (SciDAC), along with other researchers from the computational science community, gather at the annual SciDAC conference to present scientific results, discuss new technologies, and discover new approaches to collaboration.

Wright and Skinner Co-Author Book Chapter on IPM
Karl Fürlinger of UC Berkeley EECS and Nick Wright and David Skinner of NERSC recently published a chapter titled “Performance Analysis and Workload Characterization with IPM” in the Springer volume Tools for High Performance Computing 2009: Proceedings of the 3rd International Workshop on Parallel Tools for High Performance Computing, September 2009, ZIH, Dresden. The chapter is an outgrowth of DOE- and NSF-funded research into HPC performance analysis.
SLAC to Host Extremely Large Databases Conference October 6–7
The 4th Extremely Large Databases Conference (XLDB4) will be held October 6–7, 2010, at SLAC National Accelerator Laboratory in Menlo Park, California. Leading practitioners from science, industry, and academia will discuss lessons learned and real-world solutions for handling terabytes and petabytes of data. Arie Shoshani, head of CRD’s Scientific Data Management Research Group, is on the Organizing Committee. Early registration ends on July 31.
Link of the Week: Dream-Logic, the Internet and Artificial Thought
What does it mean to think? Can machines think, or only humans? Writing in Edge, David Gelernter, a professor of computer science at Yale and chief scientist at Mirror Worlds Technologies, argues that today’s mainstream ideas about human and artificial thought lead nowhere. No computer will be able to think like a human, he says, unless it can free-associate, hallucinate, and feel (or simulate) emotions. Read more.
About Computing Sciences at Berkeley Lab
The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.
ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.
Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.
DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
