NGS/Models to Support Performance-Engineering of Global Computations

支持全局计算性能工程的模型本提案的重点是支持全局计算的建模和调度方法，从而将计算网格和高性能分布式计算扩展到全局级别。为资源可用性和资源分类开发复杂的新兴全球和网格计算平台的新模型，试图统一两种平台类型的性能特征.使用这些模型，开发调度策略，实现健壮、可预测的性能，并为应用程序提供高可用性.用两个“真实世界”的全局计算应用程序验证这些方法，使用新颖的模拟技术，如果可能的话，还可以使用真实的全球计算系统。预测模型和模拟框架将促进对网格和全球计算环境的基本理解。这些发展尤其将是推进网格技术发展的关键。通过解决与两个社区相关的计算机科学研究问题来研究全球计算基础设施的艺术。

Models to Support Performance-Engineeringof Global ComputationsThis Proposal focuses on modeling and scheduling methodologies that will enable global computing,thus extending Computational Grids and high-performance distributed computing toa global level.There are three objectives to the work proposed:1. develop novel models of complex emerging global and Grid computing platforms forboth resource availability and resource classi_cation, attempting to unify the performance characteristicsof both platform types.2. Using these models, develop scheduling strategies which enable robust, predictable performanceand deliver high availability for applications.3. validate these approaches with two \real-world" global computing applications, using bothnovel simulation techniques and if possible a real global computing system.The predictive models and simulationframework will advance the foundational understanding of both Grid and global computing environments.These developments particularly will be key to advancing the state-of-the-art of the globalcomputing infrastructure by addressing the computer science research questions that are relevantto both communities.
