Maybe :-)

It's not the main focus of the project, I believe the intent was to use the 
Intel SSE intrinsics directly rather than abstracting them, since these 
appear to be available on all Intel based platforms.  Although some other 
platforms also support vectorising operations, they're predominantly for 
integer or 32-bit float operations which is less useful for our purposes 
(anyone know different?).

Indeed, thanks!
