Sound Dynamic Deadlock Prediction in Linear Time

Explore a groundbreaking approach to deadlock prediction in concurrent systems through this 15-minute video presentation from the PLDI 2023 conference. Delve into the challenges of dynamic deadlock prediction and discover a novel class of predictable deadlocks called sync-preserving deadlocks. Learn about two innovative algorithms, SPDOffline and SPDOnline, designed for sound deadlock prediction with linear time complexity. Understand the tradeoffs between soundness, precision, and efficiency in deadlock detection, and see how the new concept of sync-preserving deadlocks offers a highly effective solution. Gain insights into the implementation and evaluation of these algorithms on standard benchmarks, demonstrating their ability to characterize and detect the majority of deadlocks efficiently.
