The TAU Portable Profiling Package

What is TAU?

TAU (Tuning and Analysis Utilities) is a visual programming and performance analysis environment for parallel C++ and HPF. TAU is implemented in C and C++ and uses Tcl/Tk for graphics. The TAU tools are implemented as graphical hypertools. While they are distinct tools, they act in concert as if they were a single application. TAU is part of the HPC++ project.
