LLVM's OpenMP runtime library (libomp) provides a high-performance implementation of the OpenMP API specification for shared-memory parallel programming. This package delivers the runtime library and headers needed to execute OpenMP programs compiled with clang or other LLVM-based compilers. It supports all major OpenMP features including parallel regions, work-sharing constructs, synchronization primitives, and SIMD directives. The implementation is optimized for modern multi-core processors and provides excellent scalability across different platforms including Linux, macOS, and Windows.
