Chapter 8.3 : The vectorization of reduction

• 8.3.1) The reduction_vectorize.h
• 8.3.2) The reduction_vectorize.cpp
• 8.3.3) The main_vectorize.cpp
• 8.3.4) The CMakeLists.txt

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
