The Predictive Science Academic Alliance Program
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.
The centers focus on unclassified applications of interest to NNSA and its three national laboratories: LLNL, LANL, and SNL.
The PSAAP centers develop the science and engineering models and software for their large-scale simulations, as well as employing best practices of verification, validation, and uncertainty quantification. A crucial new aspect of their work, in the current phase of the program, is computer science research aimed at addressing the major challenges of data movement, parallel scaling, resiliency, and power consumption in emerging high-performance computing hardware.
The goal of such research is to make the most effective use of next-generation computers, which will be of completely unprecedented scale and complexity, but which promise to allow revolutionary advances in physical fidelity and accuracy.

Mark Schraad (S&E Apps)
Sriram Swaminarayan (Illinois TST Chair) (CS)
Jim Cooley (V&V)
Scott Pakin (CS)
