In very large, complex functions, loops preceded by OpenMP directives may not be threaded. Compiler may emit the warning remark: "An internal threshold was exceeded: loops may not be vectorized or parallelized. Try to reduce routine size."
Linker error generated when different parts of a program try to link both the static and dynamic versions of the OpenMP runtime. The solution is to expilcitly call out either a dynamic or static link.
The Intel® Compilers provide an OpenMP* runtime library to enable mixed Microsoft Visual C++* and Intel Compiler builds that both use OpenMP*.
This page lists fixes that have been made in Intel Professional Edition Compilers 11.1.
With automatic parallelization, the compiler detects loops that can be safely and efficiently executed in parallel and generates multithreaded code.
This article explains how to create your own OpenMP* thread mapping to OS proc IDs with Intel® C/C++ and Fortran compiler, by setting environment variable KMP_AFFINITY. It also provides some thread affinity demo results on when use different settings.

The Intel C++ and Fortran compilers for Windows* and Linux* provide 'legacy' and 'compatibility' implementations of the OpenMP THREADPRIVATE directive. The 'compatibility' option should not be used when everything is compiled by Intel compilers.
