Neither of those languages gives you portable SIMD. Rust is rapidly becoming the language of choice for high performance code.

  google has a mature C++ library for portable SIMD. The original article seems to be a translation of the excellent algorithmica site which had it in C++. https://github.com/google/highway https://github.com/google/highway

    You can do portable SIMD in GNU C/C++ using the vector extension: https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html

      I'm not sure that "portable" and "only works on one specific compiler vendor" are very compatible concepts

        gcc is available on and targets more platforms than rust. So if GNU C is not considered portable you can forget about 'portable rust'.

          Portability in the C and C++ worlds generally means across standard-conforming compilers, not just across platforms
