Abstract
A contention log contains data for contentions that occur during execution of a multi-threaded application, such as a timestamp of the contention, contention length, contending thread identity, contending thread call stack, and contended-for resource identity. After execution of the application ends, contention analysis data generated from the contention log shows developers information such as total number of contentions for particular resource(s), total number of contentions encountered by thread(s), a list of resources that were most contended for, a list of threads that were most contending, a plot of the number of contentions per time interval during execution of the application, and so on. A developer may pivot between details about threads and details about resources to explore relationships between thread(s) and resource(s) involved in contention(s). Other information may also be displayed, such as call stacks, program source code, and process thread ownership, for example.
