  • Some of the world’s fastest supercomputers are among ASC’s accomplishments in advanced computing. However, it is not all about speed. Each new system is engineered to bring certain capabilities to
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • Established in 1995, the Advanced Simulation and Computing (ASC) Program supports the U.S. Defense Programs' shift in emphasis from test-based confidence to simulation-based confidence. Under ASC,
