• Putting Vector Programming to Work with OpenMP* SIMD for Intel® Xeon® Processors, Intel® Xeon Phi™ Coprocessors, and Intel® GPUs
  This article describes the C/C++/Fortran SIMD extensions for explicit vector programming available in the OpenMP* 4.0 specification. We explain the semantics of SIMD constructs and clauses with simple examples. In addition, explicit vector programming guidelines and programming examples are provided in Sections 3 and 4 to help programmers write efficient SIMD programs.
   
• Vectorization Advisor: A New Tool for Vectorization Advice
  In this article, we demonstrate how to use Intel® Advisor XE on real code examples to optimize vector codes. Intel Advisor XE combines dynamic analysis, static binary analysis, and compiler reports with actionable recommendations for fixing performance bottlenecks.
