Looking at the SIMD.jl example vadd!(xs, ys, Vec{8,Float64}) there is a specific size 8 being set for the vec size. How do I know whether to use 4 or 8 or more? I assume it is hardware dependent, but probably there is some way to choose this at runtime?

Isn’t the fact that cnt1 and cnt2 of fixed scalar size, instead of a SIMD vector, making it impossible to perform operations involving them vectorized?
