International audience; This paper studies the interactive visualization and post-mortem analysis of execution traces generated by task-parallel programs. We focus on the detection of performance anomalies inaccessible to state-of-the-art performance analysis techniques, including anomalies deriving from the interaction of multiple levels of software abstractions, anomalies associated with the hardware, and anomalies resulting from interferences between optimizations in the application and run-time system. Building on our practical experience with the performance debugging of representative task-parallel applications and run-time systems for dynamic dependent ta...
