NGS: Collaborative Research: Performance Driven Adaptive Software Design and Control

EIA-0103756Vikram S.AdveUniversity of Illinois-Urbana该项目的目标是开发在分布式计算系统上运行的复杂应用程序的以性能为导向的集成设计和控制所需的工具。它的目标计算系统很复杂，融合了计算网格难以实现的异构性、延迟和自适应特性。它的目标应用程序处于计算科学的前沿：具有自适应特性的非常大型、复杂的应用程序，不允许在运行前评估其最佳系统配置或计算需求。每个应用程序将被视为组件的组合，并为每个组件设计一个正式的高保真性能模型。该方法是使用基于模型的自适应运行时控制，基于这些组合的性能模型来控制应用程序的执行以满足指定的性能目标。控制策略将对修改应用程序和计算平台的行为的参数进行实时更改。

EIA-0103756Vikram S. AdveUniversity of Illinois-UrbanaThe goal of this project is to develop the tools needed for performance-directed integrated design and control of complex applications running on distributed computational systems. Its target computational systems are complex, incorporating the difficult heterogeneity, latency, and adaptive properties of computational grids. Its target applications are at the cutting edge of computational science: very large, complex applications with adaptive characteristics that do not allow their optimal system configurations or computational requirements to be estimated prior to run time. Each application will be viewed as a composition of components, with a formal, high fidelity model of performance to be designed for each component. The approach is to use model-based adaptive run-time control, based on these composed performance models, to control the execution of the application to meet specified performance goals. The control strategy will make real-time changes to parameters that modify the behavior of both application and computational platform.
