  • Los Alamos National Laboratory currently is completing the installation of its new supercomputer, Trinity. A team at Los Alamos has saved millions on this installation by redesigning the wiring layout and re-engineering cable installation. Los Alamos Data Center Manager Ron Velarde leads the High...
  • Deploying some of the world’s fastest supercomputers is among ASC’s accomplishments in advanced computing. However, it is not all about speed. Each new system is engineered to bring certain capabilities to bear on the problems of modeling and simulation that will enhance the overall...
  • The Advanced Technology Development and Mitigation (ATDM) subprogram includes laboratory code and computer engineering and science projects that pursue long-term simulation and computing goals relevant to the broad national security missions of the NNSA. It addresses the need to adapt current...
  • Catalyst, a first-of-a-kind supercomputer at Lawrence Livermore National Laboratory, is available to industry collaborators to test big data technologies, architectures and applications. Developed by a partnership of Cray, Intel and Lawrence Livermore, this Cray CS300 high...
  • This sub-program provides both necessary physical facility and operational support for reliable, cross-lab production computing and storage environments as well as a suite of user services for effective use of ASC tri-lab computing resources. The scope of the facility operations includes planning,...
  • The mission of this national sub-program is to build integrated, balanced, and scalable computational capabilities to meet the predictive simulation requirements of NNSA. This sub-program strives to provide users of ASC computing resources a stable and seamless computing environment for all ASC-...
  • Verification and Validation (V&V) provides assurance that the models in the codes produce mathematically correct answers and that the answers reflect physical reality. The V&V subprogram funds the critical skills needed to apply systematic measurement, documentation, and demonstration of...
  • Models are mathematical equations and tables that describe physical entities and processes; and are the vehicle by which new scientific understanding is written into the integrated codes. This subprogram funds the critical skills charged with the development, initial validation, and incorporation...
  • Integrated codes contain the mathematical descriptions of the physical processes relating to nuclear weapon systems and describe what the nation knows about how nuclear weapons function. This subprogram funds the critical skills needed to develop, maintain and interpret the results of the large‐...
  • Established in 1995, the Advanced Simulation and Computing (ASC) Program supports the Department of Energy’s National Nuclear Security Administration (NNSA) Defense Programs’ shift in emphasis from test-based confidence to simulation-based confidence. Under ASC, scientific simulation...
