Going forward, support for additional OpenMP features will leverage LLVM’s OpenMP runtime. As a first step, we added the option to generate code compatible with LLVM’s OpenMP runtime library (libomp) on the 圆4 architecture. Starting with Visual Studio 2019 version 16.9 we have begun adding experimental support for newer versions of the OpenMP standard in a more systematic way. In the initial release of Visual Studio 2019 we added the -openmp:experimental switch to enable minimal support for the OpenMP SIMD directive first introduced in the OpenMP 4.0 standard. Microsoft Visual Studio has supported the OpenMP 2.0 standard since 2005. The OpenMP application program interface for C, C++, and Fortran was originally developed in the 1990s for this purpose, and today the standard continues to evolve to support new scenarios, such as off-loading to additional devices and providing more fine-grained control over which threads execute which tasks. ![]() As devices with multiple cores and processors became ubiquitous, programming languages adapted to provide developers with control over how tasks are divided across processors.
