广域计算网格具有为科学界提供大量计算能力的潜力。实现这种潜力需要智能的数据管理，使应用程序能够利用远程计算资源，最大限度地减少远程数据访问开销。我们定义了执行域，一个框架，它定义了一个亲和力之间的CPU和数据资源在网格中，所以应用程序被安排在CPU上运行，有必要访问数据集和存储设备。该框架还包括域管理器，动态调整执行域配置，以支持网格应用程序的有效执行代理。在本文中，我们提出了执行域框架，并展示了我们如何将其应用在秃鹰资源管理系统。(C)2001爱思唯尔科技有限公司。保留所有权利。
Wide-area computational grids have the potential to provide large amounts of computing capacity to the scientific community. Realizing this potential requires intelligent data management, enabling applications to harness remote computing resources with minimal remote data access overhead. We define execution domains, a framework which defines an affinity between CPU and data resources in the grid, so applications are scheduled to run on CPUs which have the needed access to datasets and storage devices. The framework also includes domain managers, agents which dynamically adjust the execution domain configuration to support the efficient execution of grid applications. In this paper, we present the execution domain framework and show how we apply it in the Condor resource management system. (C) 2001 Elsevier Science B.V. All rights reserved.
