Distributed Deadlock Detection

Distributed deadlock models are presented for resource and communication deadlocks. Simple distributed algorithms for detection of these deadlocks are given. We show that all true deadlocks are detected and that no false deadlocks are reported. In our algorithms, no process maintains global information; all messages have an identical short length. The algorithms can be applied in distributed database and other message communication systems. © 1983, ACM. All rights reserved.
