Abstract: The non-determinism in concurrent software obstructs the detection of deadlocks. Previous work focuses on detecting deadlocks by only using a single approach or a single tool. This paper evaluates the capabilities of contemporary deadlock detection tools. Based on the comparison results， an integrated application of deadlock detection tools is proposed， which incorporates all detection approaches from analysis， verification to testing. Moreover a set of metrics is presented to assess the detection results of these tools based on the different nature of analysis， verification and testing. The empirical results show the effectiveness of this method.

Key words: deadlock detection, tool evaluation, integrated application of tools, concurrent software

摘要： 并发软件运行的不确定性使得死锁检测十分困难。现有的工作集中在使用分析、验证或测试的单一途径来检测死锁。通过分析现有工具的死锁检测能力，提出了综合使用工具的死锁检测方法。同时根据分析、验证和测试途径的不同特点，给出了评估工具检测结果的度量方法。实验结果显示了该方法的有效性。
