Intel® C++ compiler is an industry-leading C/C++ compiler, including optimization features like auto-vectorization and auto-parallelization, OpenMP*, and Intel® Cilk™ Plus multithreading capabilities; plus the highly optimized performance libraries.
We have created a list of articles with samples explaining the features in detail and how or when to use in the source code. There are:
Intel System Studio not only provides a variety of signal processing primitives via Intel® Integrated Performance Primitives (Intel® IPP), and Intel® Math Kernel Library (Intel® MKL), but also allows developing high-performance low-latency custom code (Intel C++ Compiler with Intel Cilk Plus). Since Intel Cilk Plus is built into the compiler, it can be used where it demands an efficient threading runtime in order to extract parallelism. Therefore it's possible to effectively introduce multicore parallelism even without introducing it into each of the important algorithms e.g., by employing a parallel pattern called pipeline. For custom code (e.g., code that's not reused via a library), one can rely (in addition to auto-vectorization) on an extended Array Notation incl. elemental functions (kernels) to explicitly vectorize at a higher level compared to ISA-specific intrinsic functions.
The current OpenMP* 4.0 RC1 specification and associated TR1 technical report (both available from http://openmp.org) adds new features for controlling vectorization and execution on coprocessors. Intel® C++ Composer XE 2013 Update 2 (compiler version 13.1) supports two of these new features regarding the simd and target clauses. These are similar to existing Intel-specific compiler directives.

Intel [Visual] Fortran Composer XE 2013 Update 2 (compiler version 13.1) adds support for new features in OpenMP* 4.0. This article serves as documentation for the features until the regular product documentation is updated.
I love ARM. Yes, I do. - Why do I work for Intel then? Because I love Intel even more. That's why I'd like to help independent software vendors to port their products from ARM to Intel Architecture. But if and only if they would like to do it.
