New features

  • Runtime selective instrumentation.
  • Support load tracking with TAU_TRACK_LOAD.
  • Support jumbled command lines, e.g. tau list measurement is the same as tau measurement list.
  • Specify OpenMP measurement library on tau init, e.g. tau init --openmp=ompt.
  • New default measurements:
    • baseline: generate a profile file showing application wall clock time without instrumentation of any kind, i.e. zero overhead.
    • source-inst: automatic source-based instrumentation only.
    • compiler-inst: automatic compiler-based instrumentation only.


  • "profile" and "trace" measurements to fall back to compiler-based inst
  • tau gcc -h no longer shows TAU environment variables on stdout (compatibility with GNU autotools)
  • Change --mpi-compilers to --mpi-wrappers
  • Many bugs fixed.

Developed in part at the 2017 ORNL Hackathon at NASA with help from the NASA High Performance Computing Incubator and the FUN3D team.

The 2017 ORNL Hackathon at NASA was a collaboration between and used resources
of both the National Aeronautics and Space Administration and the Oak Ridge Leadership
Computing Facility at Oak Ridge National Laboratory. Oak Ridge Nation Laboratory is
supported by the Office of Science of the U.S. Department of Energy under Contract No. DE-AC05-00OR22725.
