How to Enable Compiler Vectorization
Enabling compiler vectorization is challenging.
This report is designed for C/C++ developers working on systems that utilize Intel® processors or compatible, non-Intel processors that support SIMD instructions such as Intel® Streaming SIMD Extensions.
It gives a detailed overview of vectorization, their proper use with compilers along with detailed coding examples.

Applying some of the vectorization techniques enabled by Intel compilers and their Intel® CilkTM Plus technologies to an example application. Here, we demonstrate the most important features and best-known methods by applying some of the vectorization techniques enabled by Intel® compilers and their Intel® CilkTM Plus technologies to an example application implementing an image processing algorithm.
