Sponsors CORAL and Other Initiatives Partnerships Academic Alliances Meetings As part of Lawrence Livermore National Laboratory, the ASC Program's funding largely comes from the NNSA Office of Defense Programs for nuclear weapons stockpile stewardship activities. [ more ] The ASC Program partners with other national laboratories and industry on many initiatives for the advancement of programmatic hardware and software, including CORAL, a collaboration for the next advanced technology high performance computing system. [ more ] ASC integrates the work of the three National Nuclear Security Administration (NNSA) Defense Programs laboratories—Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories—and university researchers nationally into a coordinated program administered by the NNSA. [ more ] The Predictive Science Academic Alliance Program (PSAAP) centers focus on the emerging field of predictive science—the application of verified and validated computational simulations to predict the behavior of complex systems where routine experiments are not feasible. [ more ] The ASC Program Office at Livermore hosts best practices meetings for the Department of Energy to address common high performance computing concerns across the complex. Understanding the best practices of all laboratories can contribute to the successful installation of new systems.
