The National Nuclear Security Administration (NNSA) Office of Advanced Simulation and Computing (ASC) held a Pre-Proposal Conference on March 14-15, 2018 at the Airport Marriott in Minneapolis, MN. Representatives from interested U.S., Ph.D.-granting institutions were present to learn about the next ASC academic program, Predictive Science Academic Alliance Program III (PSAAP III), which is a follow-on to the present ASC PSAAP II (see The three major focus areas of the new ASC Alliance program will be:

  1. Development and demonstration of technologies and methodologies to support effective Exascale computing in the context of science/engineering applications;
  2. “Predictive Science” based on verification and validation and uncertainty quantification (V&V/UQ) for large-scale simulations;
  3. Discipline-focused research needed both to further predictive science and enable Exascale computing.
