Well, I tried, and I tried, but I can't get no ... vectorization:


Did you look why?

Well, it would help if I'd know where to look. Obviously, the array has a constant bound that's divisible by (at least) 2^6, so vectorization *shouldn't* be a problem.


Oh, BTW, I checked that the computation of LOG(X) was moved out of the loop.
