# Advanced Simulation and Computing **Domain:** Austin Research / Programs **Doc Type:** Research entity **Source basis:** Supplied research cluster with linked references; see the [[wiki/Austin Research Evidence Map|evidence map]] for verification scope. **Advanced Simulation and Computing (ASC)** supplies [[wiki/National Nuclear Security Administration|NNSA]] simulation capabilities and computing resources for stockpile assessment, aging studies, life-extension work, accident scenarios, and related analysis. It oversees [[wiki/Predictive Science Academic Alliance Program|PSAAP]]’s academic research. ASC links physical experiments, numerical models, software, and high-performance computing to decisions about complex nuclear systems. The Austin significance is the methodological demand imposed on [[wiki/PECOS|PECOS]]: a calculation must come with evidence about its accuracy and uncertainty for the intended use. The corpus’s wider interpretation follows this discipline into [[wiki/Digital Twin|digital twins]] and other executable models. A historical origin in stockpile science is different from the mission and authority of a later medical or civilian application. ## Connected entries [[wiki/National Nuclear Security Administration|National Nuclear Security Administration]] · [[wiki/Predictive Science Academic Alliance Program|Predictive Science Academic Alliance Program]] · [[wiki/PECOS|PECOS]] · [[wiki/Verification Validation and Uncertainty Quantification|Verification Validation and Uncertainty Quantification]] · [[wiki/Nuclear Stockpile Stewardship|Nuclear Stockpile Stewardship]] ## Sources and corpus context - [[research/The Austin Executable Loop|The Austin Executable Loop — master document]] - [NNSA Announces Selection of the Next Round of Predictive Science Academic Alliance Program Centers](https://www.energy.gov/nnsa/articles/nnsa-announces-selection-next-round-predictive-science-academic-alliance-program) - [Overview of NNSA Programs for Students and Principal Investigators](https://www.energy.gov/nnsa/overview-nnsas-programs-students-and-principal-investigators) - [U.S. Nuclear Weapon Computer Simulations](https://2009-2017.state.gov/t/avc/rls/202014.htm) **Cluster:** [[wiki/Austin Executable Loop|Austin Executable Loop]] · [[wiki/Austin Research Evidence Map|Austin Research Evidence Map]]
