Technomathematik (= applied mathematics) Oh, I've just seen that I didn't link the thesis yet. Should be there under documentation in a few minutes >> It might be interesting to offer the use of SSE values internally.

For the IA-32 are at least the MSVC++ and the Intel ICC important, too. And my expericence (with ICC) are, that the vectorisation does only work for loops. The code of my thesis uses recursions and explicitly coded operations. The ICC wansn't able to auto vectorise any of those.
