Can all basic SIMD instructions be mapped to numpy array operations?
If so, why doesn't numpy already use them?  (Or does it?)

And if not, then is there some existing C extension module for CPython
that exposes them somehow?  Of course CPython cannot hope for
impressive speedups with such an extension module, but such a module
in PyPy could be JITted and give massive speed benefits.


A bientôt,

Armin.
