EIA-0103674Manish ParasharRutgers University The overall research goal of this proposal is to design, develop, evaluate and deploy Pragma, the next generation adaptive runtime infrastructure capable of reactively and proactively managing and optimizing application execution using current system and application state, predictive models for system behavior and application performance, and an agent based control network. The overarching motivation for this research is to enable very large-scale, dynamically adaptive scientific and engineering simulations on widely distributed and highly heterogeneous and dynamic execution environments such as the computational "grid". The design, development and evaluation of the proposed Pragma framework will be conducted in collaboration with the Astronomy Department at the University of Arizona in the context of a real-world astrophysical hydrodynamics simulation using adaptive mesh refinement and including multigroup flux-limited diffusion, self gravity, nuclear burning, and a complex equation of state.

该提案的总体研究目标是设计、开发、评估和部署Pragma，这是下一代自适应运行时基础设施，能够利用当前系统和应用程序状态、系统行为和应用程序性能的预测模型以及基于代理的控制网络，积极主动地管理和优化应用程序执行。这项研究的首要动机是在广泛分布、高度异构和动态的执行环境（如计算“网格”）上实现非常大规模、动态适应的科学和工程模拟。Pragma框架的设计、开发和评估将与亚利桑那大学天文系合作，在现实世界的天体物理流体动力学模拟背景下进行，使用自适应网格细化，包括多群通量限制扩散、自重力、核燃烧和复杂的状态方程。
