TAU Performance System® is a portable profiling and tracing toolkit for performance analysis of parallel programs written in Fortran, C, C++, Java, Python. It is capable of gathering performance information through instrumentation of functions, methods, basic blocks, and statements. All C++ language features are supported including templates and namespaces. The API also provides selection of profiling groups for organizing and controlling instrumentation. The instrumentation can be inserted in the source code using an automatic instrumentor tool based on the Program Database Toolkit (PDT), dynamically using DyninstAPI, at runtime in the Java Virtual Machine, or manually using the instrumentation API. TAU internally uses the Score-P system for generating OTF2 traces that may be visualized using the Vampir Pro toolkit.

TAU's profile visualization tool, paraprof, provides graphical displays of all the performance analysis results in aggregate and single node/context/thread forms. The user can quickly identify sources of performance bottlenecks in the application using the graphical interface. In addition, TAU can generate event traces that can be displayed with the Vampir, Paraver or JumpShot trace visualization tools.

ParaTools has contributed extensively to TAU and offers annual support contracts and training workshops for TAU. ParaTools is the sole licensee of the TAU Performance System® trademark owned by the State of Oregon acting by and through the State Board of Higher Education on behalf of the University of Oregon. It is authorized to provide consulting and support services related to the TAU project.
