python 자체적으로 auto vectorization을 지원하는지 모르겠고
-O2 밖에 안되서 어떻게 될지 모르겠지만 혹시나 cython 이라던가 이쪽에서 지원하지 않을가 해서 검색해보니
먼가 하나 나와서 테스트 중
설치는 간단하고

그나저나.. arm aarch64 에서는 neon이 활성화 되는데
10세대 모바일 프로세서에서는 왜.. haswell 이라고 하나만 활성화 될까? skylake 정도는 활성화 되어야 하는거 아닌가?

deprecated 되었다고 한다.
| Note that these features were deprecated in 3.0, and actually removed in 3.1 (but still provided compatibility via an ARB extension). In OpenGL 3.2, they moved these features into a 'compatibility' profile that is optional for driver writers to implement. |
