I love how ever example of portable SIMD isn't portable.
They specifies a constant SIMD width so it's non-portable. Well, not performance portable, but why are we using SIMD again?

Why should it be portable? Honest question.
SIMD seems to me, to be very platform specific. Maybe there are times one SIMD unit is not anothers' SIMD unit?
