Materials

Using TAU on Argonne systems

  1. Choose an appropriate TAU_MAKEFILE:

    % soft add +tau-latest
    % export TAU_MAKEFILE=/soft/perftools/tau/tau_latest/bgq/lib/Makefile.tau-bgqtimers-papi-mpi-pdt
    % export TAU_OPTIONS='-optVerbose' # (see tau_compiler.sh -help for more options)
    
    
  2. Use tau_f90.sh, tau_cxx.sh, etc. as Fortran, C++, etc. compiler:

    % mpixlf90_r foo.f90
    
    changes to
    % tau_f90.sh foo.f90
    
  3. Execute application:
    % qsub –A <queue> –q R.bc –n 256 –t 10 ./a.out
    

    Note: If TAU_MAKEFILE has "papi" in its name, set TAU_METRICS:

    % qsub --env TAU_METRICS=BGQ_TIMERS:PAPI_L2_DCM ...
    
  4. Analyze performance data:
    • pprof (for text based profile display)
    • paraprof (for GUI)
