ESnet Celebrates 25th Anniversary at SC11

A special event to celebrate the Energy Sciences Network's (ESnet's) silver anniversary and the launch of its 100 gigabit-per-second (Gbps) prototype network, the Advanced Networking Initiative (ANI), will be held tonight in Berkeley Lab's SC11 booth (512) at 7 p.m. As part of the ANI launch, Berkeley Lab researchers will stream 13.7 billion years of cosmic history from NERSC in Oakland, Calif. to the Berkeley Lab booth at the Washington State Convention Center. A special toast to ESnet, sponsored by Alcatel-Lucent will follow the demonstration. Read more.

ESnet Debuts Silver Anniversary Video

Did you know that before ESnet there were four different DOE networks? Take a peek into the fascinating history and exciting future of the ESnet scientific network with not one, but two different videos made by ESnet and its funder in the Office of Science, ASCR (Advanced Scientific Computing Research).

Berkeley Lab at SC11

This year, the Berkeley Lab's booth at SC11 will showcase a roster of world-class experts, demonstrations using the world's fastest science network and a 25th anniversary toast to ESnet. SC11 runs this week (Nov. 12-16) in Seattle. Berkeley Lab staff also made significant contributions to the conference program, including the submission of 11 papers and participation in five tutorials, four panel discussions, and leadership of seven Birds-of-a-Feather sessions.

Berkeley Develops Computational Tools for Analyzing Porous Materials

In an article published in the October 2011 issue of SIAM News, chemist Maciej Haranczyk and applied mathematicians Chris Rycroft and James Sethian describe the suite of tools they have created to speed up the evaluation of new porous materials. SIAM News is the monthly newsmagazine of the Society for Industrial and Applied Mathematics. Read more.

Michael Wehner Speaks at Conference on Greenhouse Gas Strategies in a Changing Climate

On Thursday, November 17, Berkeley Lab's Micahel Wehner will be presenting a talk titled "Modeling Regional Climate Change and Its Impacts" at an international conference, Greenhouse Gas Strategies in a Changing Climate held in San Francisco. Sponsored by the Air & Waste Management Association, conference attendees include officials from government, industry and environmental organizations. Items on the agenda include climate policy, mandatory greenhouse gas reporting, voluntary carbon reporting and much more. Read more.

When Things Don’t Add Up: Statistics, Maths and Scientific Fraud

Fraud is the exception not the rule in science, but it happens, as one recent high-profile case showed. In this month's editorial for the Conversation, CRD's Complex Systems Group Leader David Bailey and his colleague Jonathan Borwein, a mathematics professor from the University of Newcastle, explore how scientific chicaneries happen and what mathematics can bring to the equation.

ESnet's Deb Heller–Evans Shares Her Veteran's Day Story

In a Veteran's Day tribute to honor those who have served their country through military service, Today at Berkeley Lab (TABL) featured a profile of ESnet computer systems engineer Deb Heller–Evans. In the interview, Evans talked about her experience in the Navy, how it shaped her life and how it helped with her career. Read more.


This Week’s Computing Sciences Seminars

Will My Risk Parity Strategy Outperform?
Wednesday, November 16, 4:10 pm–5:00 pm, 939 Evans Hall-UC Berkeley Campus
Lisa Goldberg, Department of Statistics, University of California, Berkeley

We gauge the return-generating potential and risk inherent in four investment strategies: value weighting, a fixed mix, and levered and unlevered risk parity, over an 85-year horizon. There are three essential conclusions from our study. First, even over periods lasting decades, the specific start and end dates of a backtest can have a material effect on the results; second, transaction costs can negate apparent outperformance; third, statistical significance of findings needs to be assessed.

Link of the Week: Berkeley Lab Featured in USA Today Story on Challenges for U.S. Innovation

From dozens of low-slung buildings and state-of-the art complexes, more than 2,700 scientists, researchers, faculty and students at Berkeley Lab are concocting the latest in renewable energy, nanomaterials and supercomputers. Despite America's knack for ingenuity, the forces of change face some heavy crosswinds. A wheezing economy, a dearth of college engineering students, sagging high school math and science scores, and sinking research-and-development investments have heightened concerns about the USA's ability to compete. The article includes a slideshow of research around the Lab. 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.
