NGS: A Compiler-Enabled Model- and Measurement-Driven Adaptation Environment for Dependability and Performance

摘要：CNS-0406351下一代并行分布式计算必须具有可靠性和可预测性，才能满足日益复杂的科学和商业应用的要求。这种应用程序的大规模性质和不断变化的用户需求，加上它们必须在其中运行的不断变化的故障环境和工作负载，决定了它们的可靠性和性能必须以在线方式管理，以应对预期和观察到的故障、对系统的要求以及指定的可靠性、性能和/或功能要求的变化。该项目将创建一个支持编译器的模型驱动和测量驱动的适配环境，允许分布式应用程序在可能发生错误的情况下按预期执行。要实现这些能力，将需要在1)基于编译器的灵活可靠性机制、2)基于模型的有效在线预测和控制以及3)测量驱动和启用编译器的早期错误检测方面的基本进展和协同组合。该项目将验证和应用适应环境，将其用于科学和商业领域的两个重要应用：CARMA(毫米波天文学研究联合阵列)图像管道，一个射电天文数据密集型网格应用程序，以及IMobile，一个企业级移动服务平台。

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.
