Chapter 10 Advances in the TAU Performance System

Evolution and growth of parallel systems requires continued advances in the tools to measure, characterize, and understand parallel performance. Five recent developments in the TAU Performance System are reported. First, an update is given on support for heterogeneous systems with GPUs. Second, event-based sampling is being integrated in TAU to add new capabilities for performance observation. New wrapping technology has been incorporated in TAU’s instrumentation harness, increasing observation scope. The fourth advance is in the area of performance visualization. Lastly, we discuss our work in Eclipse Parallel Tools Platform.
