Abstract

The termination detection problem involves detecting whether an ongoing distributed computation has ceased all its activities. We investigate the termination detection problem in an asynchronous distributed system under crash-recovery model. It has been shown that the problem is impossible to solve under crash-recovery model in general. We identify two conditions under which the termination detection problem can be solved in a safe manner. We also propose algorithms to detect termination under the conditions identified.
