Purpose of this tutorial:

  • Attendees should generate profiles from interposition and instrumented code.
    • at least 1 profile of each
    • try some TAU_OPTIONS
  • Attendees learn a workflow of performance engineering and some known challenges

If time permits:

  • Start the process of getting TAU on local machine to use ParaProf locally.
