| 摘 要： | 为了实现动态、不稳定环境下的可靠P2P计算,提出了一种基于概率冗余调度的可靠P2P计算模型.该模型利用P2P任务调度成功率与资源稳定性、资源冗余度之间的概率关系计算任务调度的优化冗余度,不仅能获得较好的任务调度性能,而且在概率上保证了系统任务调度的可靠性.文中还设计了基于概率冗余的可靠任务调度算法,实验结果验证了提出的模型和算法的有效性.

| Abstract: | In order to implement reliable computing using volatile and dynamic resources of P2P computing environment, a reliable P2P computing model that achieves reliable task scheduling by probabilistic redundant resource allocation, is proposed. In the model, the optimization redundancy of task scheduling that can solve the contradiction between reliability and performance of system is obtained by probability. A probabilistic redundancy-based reliable algorithm for task scheduling is designed and the experiment results show that the proposed algorithm can improve the reliability and perform of task scheduling. |
