My original openmp code compiled with intel c++ complier parallelized well, but after i add compiler option /Qtcheck , the code no longer parallelized. I confirmed with debugging.
/Qtcheck option was set up for slow emulation runs in a debug build to check for threading consistency. It's intended to help you correct threading problems and achieve performance when you return to a release build. Thread checker has improved enough that you may not find any advantage in /Qtcheck.
