网格资源管理中的局部性调度

考虑通信实体之间的距离、可用带宽以及通信和资源使用费用，提出了抽象距离的数学模型，并结合网格资源和网格应用模型，设计了局部性网格资源调度算法，该算法在选择资源时首先考虑在同一节点的资源，其次通过抽象距离选择邻近的节点。实验表明，局部性调度在通信开销、成本、任务完成时间以及任务执行的成功率等方面都得到了改善。

Locally scheduling for grid resource management

Synthesizing the distance, available bandwidth and costs between communication entities, a formal model of abstract distance was proposed. Combining the grid resource model and the grid application model, a local resource scheduling algorithm was described, which used the abstract distance as criteria to select resource. Compared with other classic algorithms, this scheduling algorithm improved the such aspects as costs, task finishing time and successful rate of task execution, which was validated by the simulation experiments.
