Abstract
Resource contention monitoring and analysis are provided for a single system or multi-system environment. Resource contention is tracked at a task level when contention occurs by listing each owner of a resource in a blocker list and each waiter for the resource in a waiter list. Each list is ordered oldest to newest so each instance of contention is added to the end of the respective list. The resource request and contention lists are cross-linked to provide easy coordination between the resource queues and the contention lists. Techniques for analyzing contention using the lists, including deadlock analysis, are described.
