摘要
集群系统以其高可用性、高可扩展性、高性价比优势,成为关键应用场所的重要选择。文章设计和实现了一个应用于测控领域的高性能实时集群系统,对系统的体系结构和操作平台进行了阐述;针对高密度串行通信技术难点,分析了系统网络互联和流量;最后讨论了系统应用软件设计,介绍了各节点驻留的应用进程。作为国内首部投入工程实用的高性能实时集群,系统具有较高的可用性和实时性。
Cluster is an important approach to get high avail-ability,high scalability and high performance cost rate in criti-cal application field.This paper designs and implements a high performance real-time cluster system used in observation and control domain,explains the system architecture and the opera-tion platform.According to the technical difficulty of high-den-sity serial communication,this paper analyzes the systemic net-work and data transmission.Finally,it discusses the design of application software,introduces the application process of nodes.As the first domestic high performance real-time cluster practicably used in engineering,this system possesses the com-parably high availability and real-time characteristics.
