PSAAP II is a five-year program established in 2014 by the Advanced Simulation and Computing (ASC) program of the National Nuclear Security Administration to demonstrate predictive science in an extreme-scale computing environment. Five centers at University of Florida, University of Illinois at Urbana-Champaign, Stanford, University of Notre Dame, Texas A&M, and the University of Utah will focus on a diverse set of complex applications of importance to DOE.

This project will access ALCF and OLCF computing resources to demonstrate that the technologies and methodologies developed by these centers will effectively scale to extreme scale computing, simulating target applications with full physics and required resolution. The centers expect to gain insight into issues critical to the advancement to exascale computing, exposing areas where additional software research and development is needed on the path to exascale.
