This project aims to develop and implement a systematic approach, both analytic and computational, to extract compact, accurate, system level models of complex physical and engineering systems. The wide ranging methodology is to construct computationally efficient "wrappers" around fine scale, microscopic, detailed descriptions of dynamical systems (particle or molecular simulation, or partial differential equations or lattice equations). Comprehensively accounting for multiscale interactions between subgrid processes among macroscale variations ensures stability and accuracy. Based on dynamical systems theory and analysis, this approach is expected to empower systematic analysis and understanding for optimal macroscopic simulation for forthcoming exascale computing.

该项目旨在开发和实施一种分析和计算的系统方法，以提取复杂物理和工程系统的紧凑、准确的系统级模型。广泛的方法论是围绕动态系统的精细尺度、微观、详细描述（粒子或分子模拟，或偏微分方程或晶格方程）构建计算有效的“包装器”。全面考虑宏观尺度变化中子网格过程之间的多尺度相互作用可确保稳定性和准确性。基于动力系统理论和分析，这种方法有望为即将到来的百亿亿级计算提供系统分析和理解，以实现最佳宏观模拟。
