Concurrency Defect Resolution Best Practices
New techniques to help find and resolve more multithreading and multi-processing defects, faster.

Multithreaded and multiprocess application architectures help improve performance, but they also increase the risk of challenging concurrency defects such as threading deadlocks, multithreading race conditions, read-before-writes, and shared memory corruption. This paper describes concurrency defects as well as the best practices and technologies for finding and resolving them.

Best practices outlined include:

• Software execution recording - 100% reproducible defects
• Thread fuzzing to reveal more multithreading bugs such as race conditions, and deadlocks.
• Multiprocess correlation to help debug shared memory corruption more easily.
