网格应用程序具有苛刻的I/O需求。调度器必须使作业和数据接近，以满足吞吐量、可伸缩性和策略需求。大多数系统通过使作业或数据可移动来实现这一点。我们提出了一个系统，通过将执行和存储站点绑定到I/O社区中，然后参与广域系统，使作业和数据能够满足。社区中参与者之间的关系可以通过ClassAd框架来表达。框架的扩展允许社区成员表达间接关系。我们通过在一个国际分布式系统上改进一个关键高能物理模拟的性能来演示我们的I/O社区的实现。
Grid applications have demanding I/O needs. Schedulers must bring jobs and data in close proximity in order to satisfy throughput, scalability, and policy requirements. Most systems accomplish this by making either jobs or data mobile. We propose a system that allows jobs and data to meet by binding execution and storage sites together into I/O communities which then participate in the wide-area system. The relationships between participants in a community may be expressed by the ClassAd framework. Extensions to the framework allow community members to express indirect relations. We demonstrate our implementation of I/O communities by improving the performance of a key high-energy physics simulation on an international distributed system.
