The CMakeLists.txt file

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 :
