Super LU Library Is One of the Lab's Top Software Downloads


SuperLU, a general purpose library for the direct solution of large, sparse, non-symmetric systems of linear equations on high performance machines, is the second-most-frequently downloaded software developed at the Lab. SuperLU was developed by Sherry Li of CRD's Scientific Computing Group, Jim Demmel of UC Berkeley and CRD, and John Gilbert of UC Santa Barbara.

Based on download counts of various software between Oct. 1, 2004 and Sept. 1, 2005, SuperLU had 6,556 downloads. Among the 6,556 downloads, 4,361 were for sequential SuperLU, 1,125 for SuperLU DIST and 690 for SuperLU MT, with the remainder following links to earlier versions of the codes.

UCSF Center for Gender Equity Presents May 16-17 Symposium for UC Women


On May 16 and 17, 2006, the UC San Francisco Center for Gender Equity will host “Women Leaders 2006: A Symposium for Women in University Settings,” featuring some of the most highly respected and dynamic women leaders in their respective fields. This event will take place at the Parc 55 Hotel in downtown San Francisco.

The conference will offer opportunities for education, inspiration, and connection for all university women -- and particularly those at the University of California. Highlights include 30 workshops in three tracks -- Leadership, Personal Development and Communication -- a special reception, on-site bookstore, raffles and giveaways, and a Women Artisans Galleria.

Keynote speakers include Linda Williams, associate president, University of California; Angela Davis, teacher, writer, scholar, activist and author of five books, including "Women, Race and Class"; Winona LaDuke, Native American activist, environmentalist, economist, writer and vice presidential nominee of the United States Green Party; The Honorable Jackie Speier (invited), California state senator; and Jan Yanehiro, media personality and Emmy-award winning former host of "Evening" magazine.

The cost to register is $300. Complete program information and registration details are available on the Web at: www.ucsf.edu/cge/wg/programs/wls/index.html. For more information, contact Victoria Auer at vauer@genderequity.ucsf.edu or (415) 476-5222. Early registration is encouraged as past conferences have sold out.

Lawrence Livermore Names DoD's John Grosh as CASC Director


John Grosh, currently in the Office of the Secretary of Defense, has accepted the job of director of the Center for Applied Scientific Computing (CASC) at LLNL. Staff at CASC collaborate with Computing Sciences employees in a number of research areas. Grosh, who starts on April 24, served as co-chair of the inter-agency High-End Computing Revitalization Task Force, which was chartered by the White House to develop the federal plan for high-end computing. He previously oversaw key elements of the DoD High Performance Computing Modernization Program. His technical contributions include research in computational molecular dynamics and scientific visualization.


New Report Examines Future of Scientific Computing


A new report looking at the future of computer science and scientific computing has generated coverage in both Nature and the Economist. The report, called "Towards 2020 Science," was sponsored by Microsoft Research.

Here's the introduction from the Web site at http://research.microsoft.com/towards2020science/background_overview.htm:

“In the summer of 2005, an international expert group was brought together for a workshop to define and produce a new vision and roadmap of the evolution, challenges and potential of computer science and computing in scientific research in the next fifteen years.

“The resulting document, Towards 2020 Science, sets out the challenges and opportunities arising from the increasing synthesis of computing and the sciences. It seeks to identify the requirements necessary to accelerate scientific advances–particularly those driven by computational sciences and the 'new kinds' of science the synthesis of computing and the sciences is creating. Already this synthesis has led to new fields and advances spanning genomics and proteomics, earth sciences and climatology, nanomaterials, chemistry and physics.

“We hope Towards 2020 Science will act as a 'pathfinder' to new research directions in science and computing. We also hope that it will contribute to, and inform, national and international scientific debate and science policy. It is also just a start, a catalyst for more discussion, so lastly, we hope that you will find it useful, inspiring and provocative.”

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 6,000 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 DOE 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.
