Distributed deadlock detection

WebApr 7, 2024 · Deadlock detection is an important aspect of operating system design and is crucial for ensuring system stability and reliability in modern computing environments. There are different techniques for deadlock detection, including the banker’s algorithm, the resource allocation graph algorithm, and the wait-for graph algorithm. WebDeadlock detection is initiated whenever a process thinks there might be a problem. Several sites can initiate the detection at the same time. The advantages include the following: There is no central point of failure. A single node failure cannot cause a crash. There is no one site with heavy traffic due to the detection algorithm.
