Tuning and Analysis Utilities – TAU is a program and performance analysis tool framework being developed for the DOE Office of Science, ASC initiatives at LLNL, the ZeptoOS project at ANL, and the Los Alamos National Laboratory. TAU provides a suite of static and dynamic tools that provide graphical user interaction and interoperation to form an integrated analysis environment for parallel Fortran, C++, C, Java, and Python applications. In particular, a robust performance profiling facility available in TAU has been applied extensively in the ACTS toolkit. Also, recent advancements in TAU’s code analysis capabilities have allowed new static tools to be developed, such as an automatic instrumentation tool.
