Vectorizing Fortran using OpenMP* 4.x - Filling the SIMD Lanes


The Intel® Fortran Compiler adopted the OpenMP* 4.x Standard’s new SIMD clause and feature in 2014. The OpenMP SIMD directive is a portable and easy-to use feature, particularly for those already familiar with OpenMP. The SIMD feature allows Fortran programmer to more directly control vectorization and thereby extract maximum performance from modern Intel Architecture Processors. Some existing knowledge of vectorization, memory alignment, and OpenMP is helpful but not necessary. Ronald W. Green from the Intel Fortran Support team at Intel will lead this discussion of Fortran OpenMP SIMD directives and use, vectorization, and optimizations that will get your development efforts powered.


Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
