January/February 2005 University of California Science & Technology Review Lawrence Livermore National Laboratory P.O January/February 2005 University of California Science & Technology Review Lawrence Livermore National Laboratory P.O. Box 808, L-664 Livermore, California 94551 National Nuclear Security Administration’s Lawrence Livermore National Laboratory Also in this issue: • Jobs for Russian Weapons Workers • New Facility for Today’s and Tomorrow’s Printed on recycled paper. Supercomputers • Extracting Marketable Minerals from Geothermal Fluids About the Cover Livermore scientists use powerful machines and codes for computer simulations that have changed the way science is done at the Laboratory. As the article beginning on p. 4 describes, computer simulations have become powerful tools for understanding and predicting the physical universe, from the interactions of individual atoms to the details of climate change. For example, Laboratory physicists have predicted a new melt curve of hydrogen, resulting in the possible existence of a novel superfluid. The cover illustrates the transition of hydrogen from a molecular solid (top) to a quantum liquid (bottom), with a “metallic sea” added in the background. Cover design: Amy Henke Amy design: Cover About the Review Lawrence Livermore National Laboratory is operated by the University of California for the Department of Energy’s National Nuclear Security Administration. At Livermore, we focus science and technology on ensuring our nation’s security. We also apply that expertise to solve other important national problems in energy, bioscience, and the environment. Science & Technology Review is published 10 times a year to communicate, to a broad audience, the Laboratory’s scientific and technological accomplishments in fulfilling its primary missions. The publication’s goal is to help readers understand these accomplishments and appreciate their value to the individual citizen, the nation, and the world.

W In an October all-hands address, Director George Miller said his top priori- ties are investing for the future in programmatic growth and the underpinning infrastructure, as well as recruiting and retaining top talent at the Lab. In Review “It’s an incredibly exciting situation we find ourselves in,” Miller said in an earlier talk about the Lab’s strategic outlook. “If you look at the set of issues facing the country, the Laboratory has experience in all of them.” Defining “national security” broadly, Miller said the Lab will continue to make vital contributions to stockpile stewardship, homeland security, nonprolif- eration, arms control, the environment, climate change and sustainable energy. “Energy, environment and climate change are national security issues,” he said. With an eye toward accelerating the development of technologies that benefit national security and industry, the Lab partnered with Sandia-Calif. to launch the Livermore Valley Open Campus (LVOC) on the Lab’s southeast side. Construction has begun on an R&D campus outside the fence that will allow for collaboration in a broad set of disciplines critical to the fulfillment DOE/NNSA missions and to strengthening U.S. industry’s economic competitiveness, includ- If you look at the set of issues facing ing high-performance computing, energy, cyber security and environment.

Goodwin, Principal Associate Director Weapons and Complex Integration Lawrence Livermore National Laboratory Glenn Mara, Principal Associate Director for Weapons Programs Los Alamos National Laboratory The future of the US nuclear arsenal continues to be guided by two distinct drivers: the preservation of world peace and the prevention of further proliferation through our extended deterrent umbrella. Timely implementation of US nuclear policy decisions depends, in part, on the current state of stockpile weapons, their delivery systems, and the supporting infrastructure within the Department of Defense (DoD) and the Department of Energy’s National Nuclear Security Administration (NNSA).

  • Delivering Insight: the History of the Accelerated Strategic Computing
    Lawrence Livermore National Laboratory Computation Directorate Dona L. Crawford Computation Associate Director Lawrence Livermore National Laboratory 7000 East Avenue, L-559 Livermore, CA 94550 September 14, 2009 Dear Colleague: Several years ago, I commissioned Alex R. Larzelere II to research and write a history of the U.S. Department of Energy’s Accelerated Strategic Computing Initiative (ASCI) and its evolution into the Advanced Simulation and Computing (ASC) Program. The goal was to document the first 10 years of ASCI: how this integrated and sustained collaborative effort reached its goals, became a base program, and changed the face of high-performance computing in a way that independent, individually funded R&D projects for applications, facilities, infrastructure, and software development never could have achieved. Mr. Larzelere has combined the documented record with first-hand recollections of prominent leaders into a highly readable, 200-page account of the history of ASCI. The manuscript is a testament to thousands of hours of research and writing and the contributions of dozens of people. It represents, most fittingly, a collaborative effort many years in the making. I’m pleased to announce that Delivering Insight: The History of the Accelerated Strategic Computing Initiative (ASCI) has been approved for unlimited distribution and is available online at https://asc.llnl.gov/asc_history/. Sincerely, Dona L. Crawford Computation Associate Director Lawrence Livermore National Laboratory An Equal Opportunity Employer • University of California • P.O.

    About the National Science and Technology Council The National Science and Technology Council (NSTC) was established by Executive Order on November 23, 1993. This Cabinet-level council is the principal means by which the President coordinates science, space, and technology policies across the Federal government. NSTC coordinates the diverse parts of the Federal research and development enterprise. An important objective of the NSTC is the establishment of clear national goals for Federal science and technology investments in areas ranging from information technologies and health research to improving transportation systems and strengthening fundamental research. The Council prepares research and development strategies that are coordinated across Federal agencies to form a comprehensive investment package that is aimed at accomplishing multiple national goals. The NSTC Web site is: www.nstc.gov. To obtain additional information regarding the NSTC, please contact the NSTC Executive Secretariat at (202) 456-6100. About the Office of Science and Technology Policy The Office of Science and Technology Policy (OSTP) was established by the National Science and Technology Policy, Organization, and Priorities Act of 1976. OSTP’s responsibilities include advising the President in policy formulation and budget development on all questions in which science and technology are important elements; articulating the President's science and technology policies and programs; and fostering strong partnerships among Federal, state, and local governments, and the scientific communities in industry and academe. The Assistant to the President for Science and Technology serves as the Director of the OSTP and directs the NSTC on behalf of the President. The OSTP Web site is: www.ostp.gov.
