Study of the Best Checkpoint Interval in the Distributed Simulation System Based on Virtualization Technology

摘要

In order to keep the system's transfer, every once in a while, it was needed to grab a snapshot for the VM of all the nodes which were in the process of the distributed simulation system. It is very important to set the reasonable checkpoint interval for optimizing the system's average utilization rate. By establishing the mathematical model, The availability of distributed simulation system based on virtual technology is analyzed, and the solving equations for getting the biggest system availability is obtained, then the best checkpoint interval of the system fault tolerance could be obtained too, and the system fault tolerance of the simulation system was solved, which was so important to improve the effectiveness and credibility of the system.
