3.6.2.3 : The CMakeLists.txt file
The new compilation options will be :
-O3 -ftree-vectorize -march=native -mtune=native -mavx2
- -ftree-vectorize : Activate the vectorization
- -march=native : Target only the host CPU architecture for binary
- -mtune=native : Target only the host CPU architecture for optimization
- -mavx2 : Vectorize with AVX2 extention
We need to add a target to test the vectorized function and do both the performances tests and the plots :
