Abstract: CNS-0406351Next-generation parallel and distributed computing must be dependable and have predictable performance in order to meet the requirements of increasingly complex scientific and commercial applications. The large-scale nature and changing user requirements of such applications, coupled with the changing fault environment and workloads in which they must operate, dictate that their dependability and performance must be managed in an online fashion, reactingto changes in anticipated and observed faults, demands placed on the system, and changes in specified dependability, performance, and/or functional requirements. This project will create a compiler-enabled model- and measurement-driven adaptation environment that allows distributed applications to perform as expected despite faults that may occur. Achieving those capabilities will require fundamental advances in and synergistic combinations between 1) compiler-based flexible dependability mechanisms, 2) efficient online model-based prediction and control, and 3) measurement-driven and compiler-enabled early error detection. The project will validate and apply the adaptation environment by using it for two important applications from the scientific and commercial domains: the CARMA (Combined Array for Research in Millimeter-Wave Astronomy) image pipeline, a data-intensive Grid application for radio astronomy, and iMobile, an enterprise-scale mobile services platform.

摘要：为了满足日益复杂的科学和商业应用的需求，下一代并行和分布式计算必须具有可靠和可预测的性能。此类应用程序的大规模性质和不断变化的用户需求，再加上它们必须运行的故障环境和工作负载的变化，决定了它们的可靠性和性能必须以在线方式进行管理，对预期和观察到的故障、对系统的需求以及指定的可靠性、性能和/或功能需求的变化做出反应。该项目将创建一个编译器支持的模型和度量驱动的适应环境，该环境允许分布式应用程序按照预期执行，尽管可能出现错误。实现这些功能将需要在以下方面取得根本性的进步和协同组合：1)基于编译器的灵活可靠性机制，2)基于高效在线模型的预测和控制，以及3)测量驱动和编译器支持的早期错误检测。该项目将通过将其用于科学和商业领域的两个重要应用来验证和应用适应环境：CARMA（毫米波天文学联合阵列研究）图像管道，射电天文学的数据密集型网格应用，以及iMobile，企业规模的移动服务平台。
