OpenMP is arguably in a better place today than it was ten years ago. For instance, MSVC added support for newer OpenMP standards and implementations now support genuine device offloading. Indeed, OpenMP is probably the most popular parallel programming interface for C/C++/Fortran in use today.

Sure, OpenMP is not a pretty API, nor is it likely to yield best-in-class performance. But OpenMP is highly portable, it enjoys first-class support GCC and LLVM/clang, and it’s very straightforward to get “good enough” performance with minimal code changes. Personally, I think it’s wonderful.

Now there's a bold statement! What makes you think OpenMP is on the way out?
