This package delivers advanced capabilities for development of application parallelism and winning performance for the full range of Intel processorbased platforms and other compatible platforms. It includes the compiler's breadth of advanced optimization, multithreading, and processor support, as well as automatic processor dispatch, vectorization, and loop unrolling.
Intel Composer XE includes everything above plus the Intel C++ Compiler with Intel Parallel Building Blocks and Intel Integrated Performance Primitives, making it a great package for developers who need Fortran and C/C++. Take advantage of a significant price savings over purchasing individual components. For Windows users, this suite requires you to have Microsoft Visual Studio to use the C++ compilers.
High Performance Parallel Optimizer (HPO)
offers an improved ability to analyze, optimize, and parallelize more loop nests. This revolutionary capability combines vectorization, parallelization, and loop transformations into a single pass that is faster, more effective, and more reliable than prior discrete phases.
Automatic vectorizer analyzes loops and determines when it is safe and effective to execute several iterations of the loop in parallel. Vectorization and auto-parallelization have been enhanced for broader applicability and improved application performance.
Interprocedural Optimization (IPO)
Interprocedural Optimization (IPO) dramatically improves performance of small- or medium-sized functions that are used frequently, especially programs that contain calls within loops.
Loop Profiler is part of the compiler and can be used to generate low overhead loop and function profiling to show hotspots and where to introduce threads.
Profile-Guided Optimization (PGO)
Profile-Guided Optimization (PGO) improves application performance by reducing instruction-cache thrashing, reorganizing code layout, shrinking code size, and reducing branch mispredictions.
OpenMP 3.0 is supported to help simplify pragma-based development of parallelism in your C/C++ applications.
