摘　　要：随机产生失效核分布的方法不能反映众核处理器物理拓扑结构的真实状况,在评价相关拓扑重构算法的效能时有失客观性。本文针对这一现状,提出了一种基于缺陷成团效应的众核处理器失效核分布建模方法。实验表明,本方法得到的物理拓扑结构缺陷分布呈现出不同程度的成团特性,且成团效应会显著影响核级冗余技术的拓扑重构效果。The random method of generating failure-core distribution cannot reflect the real state of the physical topology of the many-core processors. Therefore, it is not objective to evaluate the efficiency of the topology reconfiguration algorithms. Considering this situation, a method of modeling the failure-core distribution for the many-core processors based on the defects clustering effect is proposed in this paper. The experiments show that the failure-core distribution in the physical topology derived by this method exhibits different degrees of clustering characteristics, and the defects clustering can significantly affect the effect of the core-level redundancy topology reconfiguration technology.
