COMPRESS-RAW-DATA

 Use the COMPRESS_RAW_DATA option to make Intel® Trace Collector store raw data in compressed format.

The compression works for raw events only. The merge process will be performed either by the stftool utility or by Intel® Trace Analyzer when you open the collected trace.

To do this:

  1. In a new configuration file, set the KEEP_RAW_EVENTS and COMPRESS_RAW_DATA to ON:

    KEEP_RAW_EVENTS ON
    COMPRESS_RAW_DATA ON

  2. Save the configuration file as my_settings_compress.conf.

  3. Set the VT_CONFIG environment variable to the directory that contains the configuration file:

    VT_CONFIG=/<configuration file path name>/my_settings_compress.conf

  4. Run the application.

    Linux* OS:

    $ mpirun -trace -n 4 ./poisson

    Windows* OS:

    > mpiexec -n 4 poisson.exe
