A Brief History of ASC and PSAAP

In 1995 the U.S. Department of Energy established the Accelerated Strategic Computing Initiative (ASCI), now known as the Advanced Simulation and Computing (ASC) program. Its purpose was to bring together the resources of three NNSA Defense Program national laboratories in a consolidated effort to achieve significant advances in computational modeling and simulation capabilities for maintaining the US nuclear stockpile. ASCI recognized some of its program objectives were only achievable by the establishment of a strong research portfolio of strategic alliances with leading U.S. academic institutions. To help meet the challenge, ASCI’s Academic Strategic Alliance Program (ASAP) was formed in 1997 to engage the U.S. academic community in advancing science-based modeling and simulation technologies. In 2008, the next phase of the alliance program, PSAAP I, continued the academic engagement, adding an emphasis on validation, verification, and uncertainty quantification. The program continued in 2014 with the establishment of PSAAP II that provided for an additional focus on computer science.  As PSAAP II come to an end NNSA’s Office of Advanced Simulation and Computing (ASC) and Institutional Research and Development Programs, Lawrence Livermore National Laboratory (LLNL), Los Alamos National Laboratory (LANL) and Sandia National Laboratories (SNL), initiated the next phase of its academic science program, PSAAP III, that started in 2020.
