摘要
设计和构建了一个高可用性冗余实时集群系统,讨论了系统并行计算的实现和冗余机组调度策略,建立了系统的M/M/N排队论模型,并依据此模型对系统进行了性能分析。经测试证明,系统具有较高的可用性和实时性,可作为周期性高强度多源浮点信息处理平台,用于军事指挥控制等实时性要求较高的领域。
According to the demand of high availability and real-time characteristics of real-time cluster system,and with regard to the effect of the capability of cluster network transmission on the system real-time performance,this paper gives a design and construction project of a redundant real-time cluster system with high availability,discusses the realization of systematic parallel computing and the scheduling strategy of redundant group.Then,this paper models the M/M/N queueing model of the system,analyses the performance according as the model.The practical test proves that this system possesses the comparably high availability and real-time characteristics,and it can be used as the platform of periodical and high intensity multi-source floating-point information processing in the C2 area.
