NERSC Helps Scientists Produce Breakthrough 3D Supernova Simulations

NERSC user Don Lamb from the University of Chicago credited the NERSC staff when he announced a breakthrough in creating 3D simulations of an exploding white dwarf star last week. In the past, scientists would have to manually insert the detonation into the programs to cause the explosion. But Lamb and his fellow researchers figured out a way to naturally detonate one, an achievement that they demonstrated at the “Paths to Exploding Stars” conference last Thursday in Santa Barbara. Read about the research and a quote from NERSC’s HPC consultant Katie Antypas, whose help enabled Lamb to meet a short deadline, at http://www.hpcwire.com/hpc/1328271.html. Images and links to movies of the simulations can be found at http://www.lbl.gov/CS/Archive/news032207.html.

LBNL to Host April Workshop on Global Security, Prosperity, and Sustainability

Berkeley Lab is scheduled to host the first of three “town hall meetings” on the proposed Global Security, Prosperity and Sustainability (GSPS) program. The meeting will be held April 17-18 in the Bldg. 66 auditorium. Subsequent meetings will be held at Argonne and Oak Ridge national labs. Watch InTheLoop for details as the meeting schedule firms up.

As proposed, GSPS is aimed at advancing the use of large-scale modeling and simulation to address pressing global needs for improved energy security, economic prosperity, and increased environmental sustainability. The past two decades of national investments in computer science and high-performance computing have helped place the United States at the forefront of many areas of science and engineering. This initiative seeks to integrate and focus the significant gains in computational science capabilities on important global challenges.

The challenge is to extend these gains over the next decade, increase the breadth of engagement (including international participation), and sustain the U.S. leadership position in the development of technical computing capabilities, systems software, computational science, and large-scale computational user facilities.

NERSC Center Featured in Newest Issue of SciDAC Review

NERSC’s high performance computing and storage resources are featured in the Hardware section of the third issue of SciDAC Review. The quarterly journal, produced by the Institute of Physics with support from DOE’s Office of Advanced Scientific Computing Research, highlights various projects under the SciDAC program. The new issue can be found online at http://www.scidacreview.org/0701/index.html.

Reminder: April Conference on Nuclear Energy Production, Simulation

The 2007 Computational Engineering and Science Conference (CESC2007), supported by the Office of Advanced Scientific Computing Research, will focus on nuclear energy production and the Global Nuclear Energy Partnership (GNEP). The meeting will be held April 10-12 at the Omni Shoreham Hotel in Washington, D.C.

CESC2007 will bring together disciplinary scientists and engineers focused on nuclear energy and reactor simulation with computer and computational scientists to identify barriers and opportunities for the effective use of high-end computing on nuclear energy research. A significant goal of this conference is to encourage collaboration across disciplinary and organizational boundaries on this global technical challenge.

Session chairs are busy organizing speakers on cutting edge topics such as Nuclear Reactor Simulation within GNEP, Nuclear Reactor Simulation Technical Barriers, CFD/Heat Transfer, Mesh Generation and Visualization, HPC Systems and Nuclear Energy, and a Policy Maker Session – Industrial and Agency Perspective.

Information about the conference, including a preliminary agenda, can be found at http://www.ces-conference.org/index.shtml.

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.
