摘　　要：实时集群能够满足实时系统不断增长的应用需求,拥有广阔的发展前景。本文在深入分析了实时集群系统调度特性的基础上,提出了一种双层调度模型,将实时集群的调度问题分解为节点与集群两个层次,大大降低了解决问题的难度。依照此模型,本文还给出了实时集群系统调度的完整解决方案,并得到了仿真实验的验证。Because real-time cluster can meet the more and more complicate requirements of real-time system, it has wide development prospects. In this paper, we propose a two-level scheduling model based on the analysis of the scheduling characteristic of real-time cluster system. The scheduling problems of real-time cluster are divided into two parts in this model, and this decreases the difficulties of the scheduling problems greatly. Finally, we give an efficient scheduling solution of system based on the model,and validate it by simulated experiment.
