Intel C++ Composer XE for Windows

What's new in Intel Composer XE:

Compiler & Libraries

• Includes Intel Composer XE package which contains the next-generation C/C++ and Fortran compilers (v 12.0) and performance and parallel libraries, Intel Math Kernel Library (Intel MKL) 10.3, Intel Integrated Performance Primitives (Intel IPP) 7.0, and Intel Threading Building Blocks (Intel TBB) 3.0.
• The latest Intel C/C++ compiler, Intel C++ Compiler XE 12.0, optimizes for the latest Intel Architecture (IA) processor, code-named Sandy Bridge, with Intel AVX support.
• The package contains Intel Parallel Building Blocks (Intel PBB), which includes advances in mixing and matching task, vector, and data parallelism in applications to better map to the multicore optimization opportunities. The technologies included are Intel Cilk Plus, Intel TBB, and Intel Array Building Blocks (Intel ArBB) (In beta, available separately).
• Support for vector optimizations with Intel AVX, with SIMD pragmas, and help in auto-parallelization for the highest performance and parallelism on the latest IA multicore CPUs are some additional capabilities.
• Intel Fortran Compiler XE 12.0 also includes several advances, among them more complete support for the Fortran 2003 standard and some support for Fortran 2008 standards, including Co-Array Fortran, vector optimizations with AVX, and help in auto-parallelization, for the highest performance and parallelism on the latest x86 multicore CPUs.
• Intel's performance libraries continue to provide an easy way to include highly optimized and automatically parallel math and scientific functions and data processing routines for high-performance users. The math library, Intel MKL 10.3, contains several enhancements, including better Intel AVX support, a summary statistics library, and enhanced C language support for LAPACK. The data processing library, Intel IPP 7.0, contains improved data compression, improved codecs, and support for Intel AVX and AES instructions.

Intel C++ Composer XE includes Intel C++ Compiler, Intel Integrated Performance Primitives, Intel Math Kernel Library, Intel Parallel Building Blocks.

Intel C++ Composer XE Benefits:

• Performance - Build faster code with less effort by utilizing optimizing compiler combined with advanced parallel programming models and libraries
• Compatible - Source and binary compatible with Microsoft Visual C++ and GCC.
• Broad Support - Runs on Windows and Linux in IDE or standalone. (dependant on which edition is purhcased)

Advanced optimizations boost performance
The compilers and libraries in Intel Composer XE offer advanced vectorization support, including support for Intel AVX. The C/C++ optimizing compiler now includes Intel Parallel Building Blocks (Intel PBB) library, which expands the types of problems that can be solved with increased scale and reliability, while also simplifying the process.

Advanced Performance Features:

• Intel Parallel Building Blocks (Intel PBB) and OpenMP* 3.0 simplifies implementing efficient parallel code.
• Optimized libraries provide math functions in Intel Math Kernel Library and functions in many other domains like compression, crypto, and image processing in Intel Integrated Performance Primitives provide automatic parallelization and performance.
• High-Performance Parallel Optimizer (HPO) offers an improved ability to analyze, optimize, and parallelize more loop nests.
• Interprocedural Optimization (IPO) dramatically improves performance of small- or medium-sized functions that are used frequently, especially programs that contain calls within loops.
• Profile-Guided Optimization (PGO) improves application performance by reducing instruction-cache thrashing, reorganizing code layout, shrinking code size, and reducing branch mispredictions.

Simplified Parallelism
Intel Parallel Building Blocks is a set of comprehensive parallel development models that support multiple approaches to parallelism. Mix and match the models that suit your unique parallel implementation needs.

• Intel Cilk Plus is the simplest way to add parallelism. It's a Intel C/C++ compiler extension with only 3 keywords that simplifies implementing simple loop and task parallel applications. It offers superior functionality by combining vectorization features with high-level loop-type data parallelism and tasking.
• Intel Threading Building Blocks is a C++ template library solution to implement loop and task parallelism. It includes scalable memory allocation, load-balancing, work-stealing task scheduling, a thread-safe pipeline and concurrent containers, high-level parallel algorithms, and numerous synchronization primitives.
• Intel Array Building Blocks (In beta now) is for software developers who write compute-intensive, data parallel algorithms. It produces scalable, portable, and deterministic parallel implementations from a single high-level, maintainable, and application-oriented specification of the desired computation.
