I would suggest taking a closer look at those links. They bring up another point in that you'll only find current, usable, robust support for SIMD in C++:

The first link is just a paper; the second is a 1.0 release that is seven years old, it only supports SSE, and it's all in French; the third is only for Mono, it only supports SSE and its SSE support is old and incomplete.

On the other hand, if you try to use SIMD types and intrinsics in C++ you'll find current and comprehensive support from the major compilers on all SIMD platforms.

(I'd love to use a current and comprehensive version of Haskell SIMD, but its just not ready for prime time.)
