The detection step is divided into two phases. Phase 1 analyzes the conditions of the system of interacting transactions, invoking phase 2 only if conditions are possible for deadlocks to occur. The proposed algorithm can be used in distributed database systems...
is a process cycle is found, a deadlock will definitely occur. If the resources have multiple instances, cycle detection is not enough to ensure a deadlock will be detected. A safety algorithm must be used in this case. This algorithm converts the resource allocation graph into...
A deadlock avoidance algorithm must do more than just avoid the state of deadlock—it must avoid all unsafe states. A “safe” state is a state from which the system can allocate resources to each task (up to the maximum they require) in some order and still avoid deadlock. The followi...
However, traditional algorithms are not suited in the environment in which the clients and resources may move freely. This paper presents a new mobile agent based algorithm, Agent Guard, for deadlock detection and resolution in distributed systems. A mobile agent visits the sites in the ...
This paper attempts a comprehensive study of deadlock detection in distributed database systems. First, the two predominant deadlock models in these systems and the four different distributed deadlock detection approaches are discussed. Afterwards, a new deadlock detection algorithm is presented. The ...

). If that call succeeds, there's no need to perform deadlock detection as the monitor was successfully acquired. If that call times out and the timeout chosen was less than the user-supplied timeout, then the full-blown deadlock detection algorithm can be run. With this, deadlocks in ...
An algorithm is devised and implemented to statically detect deadlocks in sequential models of MPI synchronization communication programs. The time and space complexity of the algorithm is O(n) where n is the amount of message in model. The algorithm is better than usual circle-detection methods ...
