CSR-AES: Interactive Parallel Platforms for Multi-ExperimentComputational StudiesScientists and engineers increasingly rely upon computational studiesinvolving multiple experiments (runs of simulation software) in domainsranging from engineering design-space exploration to drug design.This collaborative project develops foundations for a system thatfacilitates interactive computational studies involving large numbers ofexperiments, permitting the user to continuously monitor and steer howthe study unfolds, based on partial results. The work specificallytargets engineering design applications involving small-to-medium sizesimulation problems running on tightly-coupled parallel machines, andemphasizes (1) higher-level user control of the overall study; (2) reuseof data from prior experiments in carrying forward new computations; (3)dynamic management of system resources by relying on a tighter couplingbetween application and system software; and (4) software reuse based oncommon component architecture (CCA) compliance and standardization of amore permeable system-/solver-level interface.The system architecture builds upon the SCIRun2 framework andincorporates modules for translating high-level user specifications intorequired experiments, for allocating parallel machine resources toexperiments to optimize study progress, and numerical methods andalgorithms for estimating simulation time and resource costs.The primary impact of the work is expected in engineering design, withbroader applicability to additional classes of biomedical and geometricmodeling applications. The project will also have important educationalapplications, by creating hands-on simulated exploration experiences forstudents, and by training system computer scientists with a deepunderstanding of specific scientific domains, simulation frameworks, andnumerical solver interfaces.

CSR-AES：用于多实验计算研究的交互式并行平台科学家和工程师越来越依赖涉及从工程设计空间探索到药物设计等领域的多个实验（模拟软件运行）的计算研究。该合作项目为促进交互式计算的系统奠定了基础研究涉及大量实验，允许用户根据部分结果持续监控和指导研究的进展。这项工作特别针对涉及在紧耦合并行机上运行的中小型仿真问题的工程设计应用，并强调（1）总体研究的更高级别的用户控制； (2) 重复使用先前实验的数据来进行新的计算； (3)依靠应用与系统软件更紧密的耦合，对系统资源进行动态管理； (4) 基于通用组件架构 (CCA) 合规性和更具渗透性的系统/求解器级接口标准化的软件重用。该系统架构建立在 SCIRun2 框架之上，并合并了用于将高级用户规范转换为所需实验的模块，用于分配并行机器资源到实验以优化研究进度，以及用于估计模拟时间和资源成本的数值方法和算法。这项工作的主要影响预计在工程设计中，具有更广泛的影响适用于其他类别的生物医学和几何建模应用。 该项目还将具有重要的教育应用，为学生创造动手模拟探索体验，并培训系统计算机科学家深入了解特定科学领域、模拟框架和数值求解器接口。
