.gvs (GuideView openmp statistics) file format - performance

Question

Is there a format of *.gvs files, used by GuideView OpenMP performance analyser?
The "guide.gvs" is generated, f.e. by intel's OpenMP'ed programmes with
$ export LD_PRELOAD=<path_to_icc_or_redist>/lib/libiompprof5.so
$ ./openmp_parallelized_prog
$ ls -l guide.gvs

Answer 1

It s a plain text.
Here is an example of such from very short omp programme:
$ cat guide.gvs
