| Abstract: | 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. |
