An Improved Algorithms for Matrix Power Computation and Analysis of It’s Complexity
【摘要】 基于流水光总线的可重构线性阵列系统是一种建立在光总线上的并行高效计算模型。该文给出了一种LARPBS模型上改进的矩阵幂运算并行算法,并对其可扩展性和复杂性进行分析,通过分析可以看出,该算法是目前速度最快、成本最优的并行矩阵幂运算算法。
【Abstract】 Linear array with reconfigurable pipelined bus system(LARPBS )i s a parallel efficient computational model based on optical bus.This paper pre sents an improved parallel algorithm for matrix power computation on LARPBS and analyses its scalablity and complexity.By the analysis,we can see that the s peed of the parallel algorithm for the matrix power is currently the fastest one and its cost is optimal.
