The goal of this project is to advance the development and deployment of cyberinfrastructure by creating and validating performance models of strategic NSF computational science applications and by assessing the interdependence of alternative hardware, middleware, and software implementations on application performance. Performance models are parameterized functions that predict performance based on system and application attributes. Given current and projected architectural complexity, application performance increasingly depends on subtle, complex machine/code interactions. Understanding and modeling this complexity is a prerequisite to designing applications that achieve substantial fractions of peak hardware performance, configuring systems to match application needs, and designing more effective architectures.This effort will characterize the existing NSF supercomputing application workload; then to use the models developed via this characterization to evaluate alternative configurations of new systems, starting with SDSC's BG/L and PSC's Red Storm. The modeling methodology will then be extended to encompass additional systems and to assess the performance of Grid-enabled applications.

该项目的目标是通过创建和验证战略性 NSF 计算科学应用程序的性能模型以及评估替代硬件、中间件和软件实现对应用程序性能的相互依赖性，来推进网络基础设施的开发和部署。性能模型是根据系统和应用程序属性预测性能的参数化函数。鉴于当前和预计的架构复杂性，应用程序性能越来越依赖于微妙、复杂的机器/代码交互。了解和建模这种复杂性是设计可实现大部分峰值硬件性能的应用程序、配置系统以满足应用程序需求以及设计更有效架构的先决条件。这项工作将描述现有 NSF 超级计算应用程序工作负载的特征；然后使用通过此表征开发的模型来评估新系统的替代配置，从 SDSC 的 BG/L 和 PSC 的红色风暴开始。然后，建模方法将扩展到包含其他系统并评估支持网格的应用程序的性能。
