Vectorizing Fortran using OpenMP 4.x - filling the SIMD lanes

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.
