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.

支持全球计算性能工程的模型本建议侧重于支持全球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球水平。建议的工作有三个目标：1.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，试图统一这两种平台类型的性能特征。使用这些模型，制定能够实现健壮、可预测的性能并为应用程序提供高可用性的调度策略。使用两种新的模拟技术和一个真实的全球计算系统来验证这些方法。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。这些发展尤其将是通过解决与两个社区相关的计算机科学研究问题来推进全球计算基础设施的最先进水平的关键。
