摘要： 提出了一种基于任务表的集群方法,并介绍一个运用该方法的Linux实时集群平台。在运用该方法和平台构建实时集群应用系统的过程中,首先将应用对象分解为若干可并行执行的计算单元,用一个任务表来描述计算单元之间的关系;将任务表和计算单元程序模块嵌入集群平台,由集群平台完成并行任务分配、消息传递、故障容错等功能,从而实现集群计算。其中计算单元是传统串行程序模块。

Abstract: This paper presents a cluster method based on task table,and introduces a Linux real-time cluster platform based on the method.When constructing a cluster with the method and the platform,an application object is decomposed into a group of computing units;a task table is built to describe the relations between the computing units;the task table and the program modules of the computing units are embedded into the platform;the platform performs task distributing,message passing and failure-tolerance.The computing units are classic serial program modules.
