Study and Implementation of High Performance Real-Time Cluster In Observation and Control System

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.
