我们提出了并发算法,深度优先搜索的基础上,三个问题相关的模型检查:给定一个状态图,找到其强连接的组件,其中状态是在循环中,以及哪些状态是在“套索”。我们的算法通常表现出约四倍的速度比相应的顺序算法在八核机器。
We present concurrent algorithms, based on depth-first search, for three problems relevant to model checking: given a state graph, to find its strongly connected components, which states are in loops, and which states are in “lassos”. Our algorithms typically exhibit about a four-fold speed-up over the corresponding sequential algorithms on an eight-core machine.
