OpenMP 4.0 for SIMD and Affinity Features with Intel® Xeon® Processors and Intel® Xeon Phi™ Coprocessors

Continuing its long tradition of standards-based software products, Intel® has implemented new OpenMP features that enhance the usage of its hardware products. The newly-released OpenMP 4.0 specification ( contains several features that are especially useful with Intel® Xeon Phi™ coprocessors. The accelerator feature is a standardized way to program off-loading computations to such devices. The SIMD feature is a standardized way to engage the 512-bit wide SIMD capability on Intel® Xeon Phi™ coprocessors. The affinity feature gives users the ability to pin threads to cores in a new, more sophisticated way. Taken together, these OpenMP 4.0 features can help the user maximize performance on the new Intel® Xeon Phi™ coprocessors, while at the same time always applying to standard Intel® Xeon processors, preserving your software investment.
