TAU (Tuning and Analysis Utilities) is a set of tools for analyzing the performance of C, C++, Fortran and Java programs. It collects much more information than is available through prof or gprof, the standard Unix utilities, including per-process, per-thread, and per-host information, inclusive and exclusive function times, profiling groups that allow you to organize data collection, access to hardware counters on some systems, per-class and per-instance information, the ability to separate data for each template instantiation, start/stop timers for profiling arbitrary sections of code, and support for collection of statistics on user-defined events.


Major changes include SHMEM profiling for Cray and SGI, NVIDIA OpenCL and AMD OpenCL support, a tau_rewrite tool based on MAQAO, OpenSHMEM Profiling, Score-P Atomic/Context Events, OpenMP 3.0 instrumentation with Opari2, NVIDIA CUPTI v4.1, H2 database in PerfDMF, debugging with TAU_TRACK_SIGNALS, MinGW compiler support for Windows, UPC source level instrumentation using the Rose parser to support the Cray CCE compiler, and PDT 3.17 with Rose and MAQAO binary instrumentor.
