.gvs(GuideView openmp统计信息)文件格式

问题描述

限时删除！！

GuideView OpenMP性能分析器是否使用* .gvs文件格式?

Is there a format of *.gvs files, used by GuideView OpenMP performance analyser?

已生成"guide.gvs"，例如通过Intel的OpenMP程序使用

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

推荐答案

这是纯文本.

这是一个非常简短的omp程序的例子:

Here is an example of such from very short omp programme:

$ cat guide.gvs
