摘要

我们考虑调度由多个服务器组成的集群的软实时任务。每个服务器提供相同的服务，可以将传入的任务分配给其中一个服务器。我们研究的问题是，给定两种可选的方法来对到达的任务进行排队:集中式方法或分布式方法，哪种分配产生最佳性能。错过的截止日期标准用于评估这些方法。文中还考虑了调度策略对分布式方法性能的影响。

Performance evaluation of soft real-time scheduling for multicomputer cluster

We consider scheduling soft real-time tasks for a cluster which consists of multiple servers. Each server provides identical services where an incoming task can be assigned to one of the servers. The question we investigate is which assignment produces the best performance given two alternative approaches to queue the arriving tasks: a centralized approach or a distributed one. A missed deadline criterion is used to evaluate these approaches. The influence of dispatching policies on the performance of the distributed approach is also considered.
