Intel짰 Composer XE 2011 is an optimized compiler combined with high-performance libraries, advanced vectorization, support for Intel짰 Parallel Building Blocks and OpenMP*, speeding and simplifying improved multicore performance on multiple operating systems with the same code base.

혻

The performance-oriented features offered by Intel Composer XE equip developers to use C/C++ and Fortran to develop and maintain high-performance and enterprise applications on the latest Intel짰 Architecture processors, including the upcoming Intel processor code named Sandy Bridge. It is reasonable to expect a 20 percent performance bump with a simple recompile. Incorporate the advanced parallel models and libraries to gain more. Your mileage may vary so download an evaluation to see how it works on your code.

• Intel짰 C++ Composer XE offers the same benefits for developers only needing the C++ compiler.

• Intel짰 Fortran Composer XE offers the same benefits for developers only needing the Fortran compiler.

• 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.

Advanced optimizations boost performance

The compilers and libraries in Intel짰 Composer XE offer advanced vectorization support, including support for Intel짰 Advanced Vector Extensions (Intel짰 AVX). The C/C++ optimizing compiler now includes Intel짰 Parallel Building Blocks (Intel짰 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

• Intel짰 Parallel Building Blocks (Intel짰 PBB) and OpenMP* 3.0 simplifies implementing efficient parallel code.

• Optimized libraries provide math functions in Intel짰 Math Kernel Library and functions in many other domains like compression, crypto, and image processing in Intel짰 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^짰 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^짰 Cilk??Plus is the simplest way to add parallelism. It's a Intel^짰 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^짰 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^짰 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.

New Fortran Features

Intel짰 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 Intel AVX, and help in auto-parallelization, for improved performance and parallelism on the latest multicore processors.

The Fortran compiler is available in Intel짰 Composer XE
