摘要

基于事件关联技术，提出了一种新的基于ASKALON集成网格环境的分布式性能分析服务，用于实时计算动态工作流的运行时开销。我们演示了一种表达精确开销相关规则的形式化方法，包括基于模糊逻辑的多个性能契约作为服务质量参数，通过重新调度、各种运行时优化和转向技术在动态环境中强制执行。我们展示了材料化学和图形渲染领域两个实际应用的实验结果。

Online Analysis and Runtime Steering of Dynamic Workflows in the ASKALON Grid Environment

We present a new distributed performance analysis service of the ASKALON integrated Grid environment for computing runtime overheads of dynamic workflows in realtime based on event correlation techniques. We illustrate a formal method to express precise overhead correlation rules, including several performance contracts as quality of service parameters based on fuzzy logic to be enforced in dynamic environments though rescheduling, various runtime optimisations, and steering techniques. We demonstrate experimental results for two real applications from material chemistry and graphics rendering domains.
