Intel has posted a video tutorial on the use of the OpenMP 4.0 SIMD pragmas.
A series of seven videos covering performance essentials using OpenMP 4.0 Vectorization with C/C++. It provides an overview of why explicit vector programming methods are crucial to getting performance on modern many core platforms. In the series, we explore code snippets and background information on such topics as OpenMP* 4.0 Simd-enabled functions, and explicit SIMD loops, as well as techniques to help determine if targeted loops were vectorized and if not, why not. Each video is typically less than 10 minutes in length and yet provides a good starting point for developer who wishes to get started using these technologies.
