摘要
结点机性能差异及动态运行环境是导致系统运行状态忙闲不均的主要原因。该文提出了结点机差异测量的指标和方法,结合机群系统主/从计算模型和SPMD应用类型提出了3种任务分配算法。实践证明了该算法的有效性。
Difference of node machine performance and dynamic operation environment are main reasons to cause the unequal division. This paper proposes index and method of difference scaling, combines master/worker computing model with SPMD application types, and gives three kinds of load balancing algorithm. The application shows the algorithms is effective.
