| 摘 要： | 基于树型动态负载平衡架构,提出了一种静于静电力学的动态负载平衡机制的任务调度方法.根据当前网格负载状态,将节点抽象成电子,每次将任务从相互引力最大的重载节点开始迁移,以减小通信开销和数据迁移延迟.仿真结果显示这一模型较原树型结构负载平衡模型提高了紧耦合应用程序的性能.

| Abstract: | We purpose an electrostatics based dynamic load balancing strategy for the high level load balancing which adapts to tree based load balancing framework.This method according as the balance state in the grid,assuming the nodes were electron,each time choose the node whose gravitation is the biggest as the destination to migrate.Thereby our strategy can reduce the communication latency and the data migration latency.Our simulation results prove that the new electrostatics model combined with the tree based model improves tightly-coupled application performance. |
