The current OpenMP* 4.0 RC1 specification and associated TR1 technical report (both available from http://openmp.org) adds new features for controlling vectorization and execution on coprocessors. Intel® C++ Composer XE 2013 Update 2 (compiler version 13.1) supports two of these new features regarding the simd and target clauses. These are similar to existing Intel-specific compiler directives.
The product documentation will be updated to include the new features in a future major release. In the meantime, this article (in progress) documents the new features. If you have questions, comments or concerns, please ask in our User Forums or at Intel® Premier Support.
