59 rows · Clang code generation for target regions supports two modes: the SPMD and non-SPMD modes. Clang chooses one of these two modes automatically based on the way directives and clauses on those directives are used. The SPMD mode uses a simplified set of runtime functions thus increasing performance at the cost of supporting some OpenMP features.
With the release of Clang 3.8.0, OpenMP 3.1 support is enabled in Clang by default, and the OpenMP runtime is therefore built as a normal part of the Clang build, and distributed with the binary distributions.You do not, therefore, need explicitly to check out this code, or build it out of tree; a normal Clang check out and build will automatically include building these runtime libraries.

Clang supports the following OpenMP 5.0 features The reduction -based clauses in the task and target -based directives. Support relational-op != (not-equal) as one of the canonical forms of random access iterator. Support for mapping of the lambdas in target regions.

Clang supports two data-sharing models for Cuda devices: Generic and Cuda modes. The default mode is Generic. Cuda mode can give an additional performance and can be activated using the -fopenmp-cuda-mode flag. In Generic mode all local variables that can be shared in the parallel regions are stored in the global memory.

The Clang community has announced the availability of a full OpenMP 3.1 support implementation in the Clang compiler: “This project implements OpenMP support in the Clang C language family front-end for the LLVM compiler. The current scope of the project is to support the OpenMP 3.1 specification.”

Coming from Android Studio it was sufficient to add "-fopenmp" to the compiler flags. VS seems to support equal compilers in this template gcc 4.9 and clang 3.8. I read that under "Configuration Properties -> C/C++ -> Language" there should be an option to enable OpenMP support, but in case of this template the option is not there.

To build clang with OpenMP support just follow the clang/LLVM compiler's standard build procedure (see Getting Started: Building and Running Clang). Using To use the newly installed compiler, add the following to your environment.

The announcement seems clear on not supporting Clang for Windows. Intel compilers include commitment to supporting more new OpenMP features than Microsoft, although full OpenMP 3.1 in Intel C++ front end may be a year away.

May 22, 2015 · Clang implementation of OpenMP standard relies on LLVM OpenMP runtime library, available at http://openmp.llvm.org/. This runtime supports ARM® architecture processors, PowerPC™ processors, 32 and 64 bit X86 processors and provides ABI compatibility with GCC and Intel's existing OpenMP compilers.
