Parallel Random Walk for P/G Analysis

Abstract

This paper introduced parallel computing techniques to improve random walk algorithm. The random walk problem was firstly explained by a formal model. And then, the parallel features of random walk algorithm were discussed in detail. A parallel random walk algorithm was proposed and applied to analyze the VLSI power grid. The time complexity and the main factors impacting on the execution time of algorithm were analyzed carefully. The experimental results proved that the parallel computing techniques could improve random walk algorithm effectively.
