SAL Home PARALLEL Tools & Utilities


Understanding the performance of complex parallel applications can be very difficult. Tuning and bottleneck elimination is impossible without knowing where a code spends time, and where the bottlenecks are. TAU (Tuning and Analysis Utilities) is a set of tools that allows one to analyze the performance of parallel application programs. It is normally used by inserting TAU macros for program instrumentation into source code, compiling and running the program to generate a trace file, and viewing the trace file with TAU tools, or a third-party visualizer such as VAMPIR. TAU collects much more information than is available through prof or gprof, the standard Unix utilities.
