对一个分布式终止探测算法的改进

Improvement of a Distributed Termination Detection Algorithm

DTD(distributed termination detection)是分布式算法研究中的一个重要问题.如果不能探测计算的终止,算法就失去了其现实意义.Mattern提出的credit-recovery算法实现了消息最优,但只局限于在集中式计算中应用.对其进行了改进,使其能够应用在非集中式计算中,以更适合分布式环境.

DTD (distributed termination detection) is an important problem in the field of distributed algorithm research. If the termination of a computation can not be detected, the algorithm will lose its realistic significance. The credit-recovery algorithm proposed by Mattern is message optimal, but it is limited to centralized computation. In this paper, this algorithm is improved to be available in decentralized computation, which makes it more applicable to distributed environment.
