Safety and Security Challenge
SAFETY AND SECURITY CHALLENGE TOP SUPERCOMPUTERS IN THE WORLD - FEATURING TWO of DOE’S!! Summary: The U.S. Department of Energy (DOE) plays a very special role in In fields where scientists deal with issues from disaster relief to the keeping you safe. 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. -
NNSA — Weapons Activities
Corporate Context for National Nuclear Security Administration (NS) Programs This section on Corporate Context that is included for the first time in the Department’s budget is provided to facilitate the integration of the FY 2003 budget and performance measures. The Department’s Strategic Plan published in September 2000 is no longer relevant since it does not reflect the priorities laid out in President Bush’s Management Agenda, the 2001 National Energy Policy, OMB’s R&D project investment criteria or the new policies that will be developed to address an ever evolving and challenging terrorism threat. The Department has initiated the development of a new Strategic Plan due for publication in September 2002, however, that process is just beginning. To maintain continuity of our approach that links program strategic performance goals and annual targets to higher level Departmental goals and Strategic Objectives, the Department has developed a revised set of Strategic Objectives in the structure of the September 2000 Strategic Plan. For more than 50 years, America’s national security has relied on the deterrent provided by nuclear weapons. Designed, built, and tested by the Department of Energy (DOE) and its predecessor agencies, these weapons helped win the Cold War, and they remain a key component of the Nation’s security posture. The Department’s National Nuclear Security Administration (NNSA) now faces a new and complex set of challenges to its national nuclear security missions in countering the threats of the 21st century. One of the most critical challenges is being met by the Stockpile Stewardship program, which is maintaining the effectiveness of our nuclear deterrent in the absence of underground nuclear testing. -

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. -

Palmer Department of Nuclear Engineering Oregon State University Corvallis, Oregon 97331 [email protected] ABSTRACT KULL is a three dimensional, time dependent radiation hydrodynamics simulation code under development at Lawrence Livermore National Laboratory. A part of the U.S. Department of Energy’s Accelerated Strategic Computing Initiative (ASCI), KULL’s purpose is to simulate the physical processes in Inertial Confinement Fusion (ICF) targets. The National Ignition Facility, where ICF experiments will be conducted, and ASCI are part of the experimental and computa- tional components of DOE’s Stockpile Stewardship Program. This paper provides an overview of ASCI and describes KULL, its hydrodynamic simulation capability and its three methods of simulating radiative transfer. Particular emphasis is given to the parallelization techniques essen- tial to obtain the performance required of the Stockpile Stewardship Program and to exploit the massively parallel processor machines that ASCI is procuring. 1. INTRODUCTION With the end of underground nuclear testing, the United States must rely solely on non-nuclear experiments and numerical simulations, together with archival underground nuclear test data, to certify the continued safety, performance, and reliability of the nation’s nuclear stockpile. -

IBM US Nuke-Lab Beast 'Sequoia' Is Top of the Flops (Petaflops, That Is) | Insidehpc.Com

But the question everyone will be asking at the International Super Computing conference in Hamburg, Germany today is whether this is the last hurrah for such monolithic parallel machines and whether the move toward hybrid machines where GPUs or other kinds of coprocessors do most of the work is inevitable. No one can predict the future, of course, even if they happen to be Lawrence Livermore National Laboratory (LLNL) and even if they happen to have just fired up IBM’s “Sequoia” BlueGene/Q beast, which has been put through the Linpack benchmark paces, delivering 16.32 petaflops of sustained performance running across the 1.57 million PowerPC cores inside the box. Sequoia has a peak theoretical performance of 20.1 petaflops, so 81.1 per cent of the possible clocks in the box that could do work running Linpack did so when the benchmark test was done. LLNL was where the original BlueGene/L super was commercialized, so that particular Department of Energy nuke lab knows how to tune the massively parallel Power machine better than anyone on the planet, meaning the efficiency is not a surprise.
