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.
Compiling an application with the -openmp option that does not contain OpenMP pragmas causes a segmentation fault due to stack size overrun.
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.
Advice and background information is given on typical issues that may arise when threading an application using the Intel Fortran Compiler and other software tools, whether using OpenMP, automatic parallelization or threaded libraries.
This note explains how to configure the Weather Research & Forecasting (WRF) run-time environment in order to achieve best performance and scalability on Intel® architecture with Intel® software tools.
With automatic parallelization, the compiler detects loops that can be safely and efficiently executed in parallel and generates multithreaded code.
