基于簇结构的分层调度器的设计和实现

Design and Implementation of a Hierarchical Scheduling Model on Cluster

1 引言目前,工作站性能大幅度提高,高速网络技术日益成熟,工作站网络(NOW,Network Of Workstations)得到迅猛的发展。但随着网络环境日趋大规模化,传统方式下基于节点的调度方式显然已不能适应,因为随着节点数目的增多不仅管理更加复杂,而且系统开销也将增加很多,所以我们提出层次调度方式。

In this paper we present a cooperative scheduling model based on hierarchical cluster structure in a large-scale NOW environment- In our model ,the nodes in NOW are stratified according to their physical characteristics,and scheduling is performed across all the layers cooperatively in phases to allocate the batch tasks and interactive tasks efficiently and rationally. In this way,high throughput and low response time are achieved at the same time. The performance evaluation has shown good efficiency.
