Chapter 7.3 : The vectorization of Saxpy
- 7.3.1) The main_vectorize.cpp
- 7.3.2) The CMakeLists.txt
- 7.3.3) The compilation
- 7.3.4) The performances
We, again, have to inform the compiler :
- The tables (or pointers) are aligned with __builtin_assume_aligned
- The tables (or pointers) do not overhead eachother with __restrict__
- Enable the vectorization with -O3 -ftree-vectorize -march=native -mtune=native -mavx2
