Michael Wehner Selected as a Lead Author for the 2013 National Climate Assessment Report

Michael Wehner, a climate researcher in Berkeley Lab's Computational Research Division, has been selected as a member of the lead author team for the 2013 National Climate Assessment (NCA) report. Published every four years by the U.S. Global Change Research Program (USGCRP), the National Climate Assessment integrates new information on climate science into the context of larger social, ecological, and policy systems. It is intended to report current climate change impacts and vulnerabilities, evaluate the effectiveness of mitigation and adaption activities, identify knowledge gaps, and to aid the federal government to prioritize climate science investments. The USGCRP began as a presidential initiative in 1989 and was mandated by Congress in the Global Change Research Act of 1990, which called for "a comprehensive and integrated United States research program which will assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change." The report will be published in June 2013.

In addition to this new role, Wehner is currently a lead author of Chapter 12, "Long-Term Climate Change: Projections, Commitments and Irreversibility," in the Working Group I contribution to the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). Wehner and Berkeley Lab's Evan Mills, also contributed to the NCA report published in June 2009, read the press release here.

Lab Staff Invited to CITRIS Workshop on NX NASTRAN Software

CITRIS, the Center for Information Technology Research in the Interest of Society, is sponsoring a two-day workshop on Siemens NX CAE Training to be held January 10– 11 on the UC Berkeley campus. The workshop will be held from 8:30 a.m.– 4:30 p.m. each day in 250 Sutardja Dai Hall. The first day includes an Introduction to NX NASTRAN and Fundamentals of NASTRAN. The second day will cover NX Advanced Simulation Processes.

NX is a next-generation digital product development system with a suite of integrated, fully associative CAD/CAM/CAE applications. NX NASTRAN is a premium computer-aided engineering (CAE) tool for critical engineering computing needs to produce safe, reliable and optimized designs within increasingly shorter design cycle times.

This training program is open to all four CITRIS campuses (UC Berkeley, Davis, Merced and Santa Cruz) and LBNL. Advanced signups are required (http://www.doodle.com/qbry7igm9xiz53mu) and the deadline to sign up is Jan. 8. Space is very limited. For more information, contact Masoud Nikravesh, Nikravesh@eecs.berkeley.edu, 510-643-4522.

Winter 2012 Joint Techs Call for Participation Closes Thursday

Since 1998, the Joint Techs conference series, co-sponsored by the Department of Energy's ESnet Site Coordinating Committee (ESCC) and Internet2, brings together networking experts from research organizations for four days of in-depth discussions, workshops, tutorials, demonstrations and presentations. The conference addresses pressing challenges facing research and education networks, which serve the vast bandwidth needs of research institutions worldwide.

Abstracts for all plenary talks, working-group, birds-of-a-feather sessions, industry updates, tutorials and side meetings for the Winter 2012 ESCC/Internet2 Joint Techs meeting are due by this Thursday, December 8. The Winter 2012 Joint Techs meeting will be hosted by the Louisiana Optical Network (LONI) at the C.B. Pennington Jr. Biomedical Research Center on January 22-26 and will focus on the theme of Enhancing Infrastructure Support for Data Intensive Science.

Berkeley Lab Reaches Out to Women in Computing

Although, women comprise the majority of the United States labor force, 60 percent of college graduates in developed countries, most of the of internet users, and start the majority of new companies created each year in the US, they have made surprisingly few inroads into high performance computing, according to a recent editorial in HPCWire. This month, Berkeley Lab Computing Sciences staff reached out to this group at the Grace Hopper Celebration in Portland, Ore.

And back in back in Oakland, Calif., Katie Antypas who heads NERSC's User Services Group gave students from Mills College, historically a college for women, a lesson in parallel computing and a tour of the facility's supercomputers. This group also included a co-ed contingent from Mills College's graduate program. Read More.

This Week's Computing Sciences Seminar

Growing Black Holes in galaxy cores: Enhanced performance of astrophysical simulations on GPU clusters

Friday, December 9
Conference room 50B-4205 from 3:00 p.m. to 4 p.m.
Jose Fiestas Iquira
Advanced Technologies Group

We improve performance and scalability of non-standard simulations of evolving stellar systems using several GPU clusters. We apply N-body algorithms to the evolution of growing Black Holes in axisymmetric collisional galaxy cores (e.g. M32, M33, NGC205, Milky Way). We obtained a strong scaling in space (10 -7 to 102 pc) and time (Myr to Gyr), required by these systems, allowing simultaneously a dramatic reduction of execution time and high performance through massive parallelism. Our studies contribute for a better understanding of the dynamics, secular gravitational instabilities, and central rotation, among other physical properties of these systems.

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.
