ABSTRACT:
An arrangement is provided for detecting deadlocks in a multithreaded program. When a thread in a multithreaded program performs a resource operation related to a mutually exclusive shared resource, it creates relationships between the thread and the shared resource as well as between the thread and other threads of the multithreaded program. Such created relationships are monitored and used to detect deadlocks.
