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.

Building a foundational framework Editor in high performance computing Yasmin Dennig Contributing Writers Megan Davidson Sandia National Laboratories has a long history of significant contributions to the high performance computing Mattie Hensley community and industry. Our innovative computer architectures allowed the United States to become the first to break the teraflop barrier—propelling us to the international spotlight. Our advanced simulation and modeling capabilities have been integral in high consequence US operations such as Operation Burnt Frost. Strong partnerships with industry leaders, such as Cray, Inc. and Goodyear, have enabled them to leverage our high performance computing capabilities to gain a tremendous competitive edge in the marketplace. Contributing Editor Laura Sowko As part of our continuing commitment to provide modern computing infrastructure and systems in support of Sandia’s missions, we made a major investment in expanding Building 725 to serve as the new home of high performance computer (HPC) systems at Sandia. Work is expected to be completed in 2018 and will result in a modern facility of approximately 15,000 square feet of computer center space. The facility will be ready to house the newest National Nuclear Security Administration/Advanced Simulation and Computing (NNSA/ASC) prototype Design platform being acquired by Sandia, with delivery in late 2019 or early 2020. This new system will enable continuing Stacey Long advances by Sandia science and engineering staff in the areas of operating system R&D, operation cost effectiveness (power and innovative cooling technologies), user environment, and application code performance.

DOE has two supercomputers in the top ten supercomputers in electric grid, simulations provide real-time situational awareness to the whole world. Titan is the name of the supercomputer at the Oak Ridge inform decisions. DOE supercomputers have helped the Federal National Laboratory (ORNL) in Oak Ridge, Tennessee. Sequoia is the name of Bureau of Investigation find criminals, and the Department of the supercomputer at Lawrence Livermore National Laboratory (LLNL) in Defense assess terrorist threats. Currently, ORNL is building a Livermore, California. How do supercomputers keep us safe and what makes computing infrastructure to help the Centers for Medicare and them in the Top Ten in the world? Medicaid Services combat fraud. An important focus lab-wide is managing the tsunamis of data generated by supercomputers and facilities like ORNL’s Spallation Neutron Source. In terms of national security, ORNL plays an important role in national and global security due to its expertise in advanced materials, nuclear science, supercomputing and other scientific specialties. Discovery and innovation in these areas are essential for protecting US citizens and advancing national and global security priorities. Titan Supercomputer at Oak Ridge National Laboratory Background: ORNL is using computing to tackle national challenges such as safe nuclear energy systems and running simulations for lower costs for vehicle Lawrence Livermore's Sequoia ranked No.

    Technical Issues in Keeping the Nuclear Stockpile Safe, Secure, and Reliable

    Technical Issues in Keeping the Nuclear Stockpile Safe, Secure, and Reliable Marvin L. Adams Texas A&M University Sidney D. Drell Stanford University ABSTRACT The United States has maintained a safe, secure, and reliable nuclear stockpile for 16 years without relying on underground nuclear explosive tests. We argue that a key ingredient of this success so far has been the expertise of the scientists and engineers at the national labs with the responsibility for the nuclear arsenal and infrastructure. Furthermore for the foreseeable future this cadre will remain the critical asset in sustaining the nuclear enterprise on which the nation will rely, independent of the size of the stockpile or the details of its purpose, and to adapt to new requirements generated by new findings and changes in policies. Expert personnel are the foundation of a lasting and responsive deterrent. Thus far, the United States has maintained a safe, secure, and reliable nuclear stockpile by adhering closely to the designs of existing “legacy” weapons. It remains to be determined whether this is the best course to continue, as opposed to introducing new designs (as envisaged in the original RRW program), re-using previously designed and tested components, or maintaining an evolving combination of new, re-use, and legacy designs. We argue the need for a stewardship program that explores a broad spectrum of options, includes strong peer review in its assessment of options, and provides the necessary flexibility to adjust to different force postures depending on evolving strategic developments. U.S. decisions and actions about nuclear weapons can be expected to affect the nuclear policy choices of other nations – non-nuclear as well as nuclear – on whose cooperation we rely in efforts to reduce the global nuclear danger.

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.
