Tutorial: Reducing Trace File Size for Intel® Trace Analyzer and Collector
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:
In a new configuration file, set the KEEP_RAW_EVENTS and COMPRESS_RAW_DATA to ON:
KEEP_RAW_EVENTS ON
COMPRESS_RAW_DATA ON
Save the configuration file as my_settings_compress.conf.
Set the VT_CONFIG environment variable to the directory that contains the configuration file:
VT_CONFIG=/<configuration file path name>/my_settings_compress.conf
Run the application.
Linux* OS:
$ mpirun -trace -n 4 ./poisson
Windows* OS:
> mpiexec -n 4 poisson.exe
