  • Thank you for your interest in the activities of the Lawrence Livermore National Laboratory Computation Directorate. This collection of articles from the Laboratory's Science & Technology Review highlights the most significant computational projects, achievements, and contributions during 2002. In 2002, LLNL marked the 50th anniversary of its founding. Scientific advancement in support of our national security mission has always been the core of the Laboratory. So that researchers could better under and predict complex physical phenomena, the Laboratory has pushed the limits of the largest, fastest, most powerful computers in the world. In the late 1950's, Edward Teller--one of themore » LLNL founders--proposed that the Laboratory commission a Livermore Advanced Research Computer (LARC) built to Livermore's specifications. He tells the story of being in Washington, DC, when John Von Neumann asked to talk about the LARC. He thought Teller wanted too much memory in the machine. (The specifications called for 20-30,000 words.) Teller was too smart to argue with him. Later Teller invited Von Neumann to the Laboratory and showed him one of the design codes being prepared for the LARC. He asked Von Neumann for suggestions on fitting the code into 10,000 words of memory, and flattered him about ''Labbies'' not being smart enough to figure it out. Von Neumann dropped his objections, and the LARC arrived with 30,000 words of memory. Memory, and how close memory is to the processor, is still of interest to us today. Livermore's first supercomputer was the Remington-Rand Univac-1. It had 5600 vacuum tubes and was 2 meters wide by 4 meters long. This machine was commonly referred to as a 1 KFlop machine [E+3]. Skip ahead 50 years. The ASCI White machine at the Laboratory today, produced by IBM, is rated at a peak performance of 12.3 TFlops or E+13. We've improved computer processing power by 10 orders of magnitude in 50 years, and I do not believe there's any reason to think we won't improve another 10 orders of magnitude in the next 50 years. For years I have heard talk of hitting the physical limits of Moore's Law, but new technologies will take us into the next phase of computer processing power such as 3-D chips, molecular computing, quantum computing, and more. Big computers are icons or symbols of the culture and larger infrastructure that exists at LLNL to guide scientific discovery and engineering development. We have dealt with balance issues for 50 years and will continue to do so in our quest for a digital proxy of the properties of matter at extremely high temperatures and pressures. I believe that the next big computational win will be the merger of high-performance computing with information management. We already create terabytes--soon to be petabytes--of data. Efficiently storing, finding, visualizing and extracting data and turning that into knowledge which aids decision-making and scientific discovery is an exciting challenge. In the meantime, please enjoy this retrospective on computational physics, computer science, advanced software technologies, and applied mathematics performed by programs and researchers at LLNL during 2002. It offers a glimpse into the stimulating world of computational science in support of the national missions and homeland defense.« less
  • In 1952, we began laboratory operations in the barracks building of the Naval Air Station with approximately 50 employees. Today, the Chemistry and Materials Science (CMS) Directorate is a major organization at the Lawrence Livermore National Laboratory with more than 500 employees who continue to contribute to our evolving national security mission. For more than half a century, the mission of the Laboratory revolved primarily around nuclear deterrence and associated defense technologies. Today, Livermore supports a broad-based national security mission, and our specialized capabilities increasingly support emerging missions in human health and energy security. In the future, CMS will playmore » a significantly expanded role in science and technology at the intersection of national security, energy and environment, and health. Our world-class workforce will provide the science and technology base for radically innovative materials to our programs and sponsors. Our 2005 Annual Report describes how our successes and breakthroughs follow a path set forward by our strategic plan and four organizing research themes, each with key scientific accomplishments by our staff and collaborators. Organized into two major sections-research themes and dynamic teams, this report focuses on achievements arising from earlier investments that address future challenges. The research presented in this annual report gives substantive examples of how we are proceeding in each of these four theme areas and how they are aligned with our national security mission. Research Themes: (1) Materials Properties and Performance under Extreme Conditions--We are developing ultrahard nanocrystalline metals, exploring the properties of nanotubes when exposed to very high temperatures, and engineering stronger materials to meet future needs for materials that can withstand extreme conditions. (2) Chemistry under Extreme Conditions and Chemical Engineering to Support National-Security Programs--Our recent discovery of a new source of coherent light adds a new tool to an array of methods we use to more fully understand the properties of materials. Insights into the early stages of polymer crystallization may lead to new materials for our national-security mission and private industry. (3) Science Supporting National Objectives at the Intersection of Chemistry, Materials Science, and Biology--We are improving drug binding for cancer treatment through the use of new tools that are helping us characterize protein-antibody interactions. By probing proteins and nucleic acids, we may gain an understanding of Alzheimer's, Mad Cow, and other neurodegenerative diseases. (4) Applied Nuclear Science for Human Health and National Security--Our work with cyanobacteria is leading to a fuller understanding of how these microorganisms affect the global carbon cycle. We are also developing new ways to reduce nuclear threats with better radiation detectors. Dynamic Teams: The dynamic teams section illustrates the directorate's organizational structure that supports a team environment across disciplinary and institutional boundaries. Our three divisions maintain a close relationship with Laboratory programs, working with directorate and program leaders to ensure an effective response to programmatic needs. CMS's divisions are responsible for line management and leadership, and together, provide us with the flexibility and agility to respond to change and meet program milestones. The three divisions are: Materials Science and Technology Division; Chemistry and Chemical Engineering Division; and Chemical Biology and Nuclear Science Division. By maintaining an organizational structure that offers an environment of collaborative problem-solving opportunities, we are able to nurture the discoveries and breakthroughs required for future successes. The dynamic teams section also presents the work of CMS's postdoctoral fellows, who bring to the Laboratory many of the most recent advances taking place in academic departments and provide a research stimulus to established research teams. Postdoctoral fellows are selected for their scientific expertise, capability, and enthusiasm for working in a highly productive environment that places a premium on scientific innovation.« less
  • The Laser Science and Technology (LS&T) Program's mission is to develop advanced lasers, optics, materials technologies, and applications to solve problems and create new capabilities of importance to the nation and the Laboratory. A top, near-term priority is to provide technical support in the deployment and upgrade of the National Ignition Facility (NIF). Our other program activities synergistically develop technologies that are consistent with the goals of the NIF Directorate and develop state-of-the-art capabilities. The primary objectives of LS&T activities in 2002 have been fourfold--(a) to support deployment of hardware and to enhance laser and optics performance for NIF, (b)more » to develop high-energy petawatt laser science and technology for the Department of Energy (DOE), (c) to develop advanced solid-state laser systems and optical components for the Department of Defense (DoD), and (d) to invent, develop, and deliver improved concepts and hardware for other government agencies and industry. LS&T activities during 2002 focused on seven major areas: (1) NIF Project-LS&T led major advances in the deployment of NIF Final Optics Assembly (FOA) and the development of 30.1 optics processing and treatment technologies to enhance NIF's operations and performance capabilities. (2) Stockpile Stewardship Program (SSP)-LS&T personnel continued development of ultrashort-pulse lasers and high-power, large-aperture optics for applications in SSP, extreme-field science and national defense. To enhance the high-energy petawatt (HEPW) capability in NIF, LS&T continued development of advanced compressor-grating and front-end laser technologies utilizing optical-parametric chirped-pulse amplification (OPCPA). (3) High-energy-density physics and inertial fusion energy-LS&T continued development of kW- to MW-class, diode-pumped, solid-state laser (DPSSL). (4) Department of Defense (DoD)-LS&T continued development of a 100 kw-class solid-state heat-capacity laser (SSHCL) for missile defense. (5) Nuclear energy applications-LS&T continued to develop laser-shock peening technology to improve the service lifetime of metal nuclear waste containment canisters designed for DOES Yucca Mountain Project. (6) Materials processing-Under cooperative research and development agreements (CRADA) with U.S. industry, LS&T developed and delivered kW-class solid-state lasers for shock peening and hole drilling of metals. (7) Diffractive optics for space telescopes and petawatt lasers-LS&T continued fabrication of large-aperture beam sampling gratings (BSGs) for NIF, and development of large-scale, lightweight diffractive optics for the next generation of space telescope (Eyeglass).« less
  • This second annual report highlights research activities in computer science and numerical analysis carried out within the Computation Directorate of the Lawrence Livermore National Laboratory (LLNL). Its purpose is to provide a technical introduction to current areas of study and to report on recent progress. Research features a heavy emphasis on multiprocessing. Although multiprocessing plays a major role in nearly every proposed new supercomputer system, much work needs to be done before we can understand how to use it effectively. In addition to multiprocessing studies, strong efforts are continuing in some of the more traditional areas of computer science, particularlymore » numerical methods.« less
  • The topics of research presented here reflect our view of the broad range of issues we need to address in support of our computing environment. Large-scale Scientific Computations represents one of our newest ventures. The goal is to more closely link expertise in the problem domains (e.g., fluid dynamics) with expertise in sophisticated numerical methods, thus allowing for a broader range of solution strategies to get better answers. Parallel Numerical Algorithms focuses more tightly on the development and analysis of numerical techniques for use in parallel computing situations. Issues here include the solution of extremely large partial differential equations, matrixmore » solution techniques, and Monte Carlo programming techniques. In the area of General Numerical Algorithms we recognize the need for a significant amount of research on numerics without the additional complexity of parallelism. This area includes work on partial differential equations, ordinary differential equations, interpolation, and a variety of statistical analysis. Parallel Systems Software addresses issues related to going from a parallel algorithm to its correct and efficient implementation on a particular system. Distributed Operating Systems and Networks describes our efforts to provide a very flexible environment for users to access a diverse set of machines and services in an efficient and simple manner. Expert Systems Software covers another relatively new and expanding area. We are looking at various ways that knowledge engineering ideas can reduce development time for writing new code systems and improve our control over experimental processes. In the section on General Purpose Software we include several projects that span a wide range of topics. The last section, Technology Information Systems, reports the status of a special effort to provide sophisticated methods for allowing users to access remote information centers.« less
