Hi,

nice work! I have waited to see this going into review.
I would be happy to try this out on my code that currently uses compiler 
vectorization.

The documentation looks good. May I ask one or two things?

1. Is simd::pack a POD? i.e. can aligned memory be cast into a pack?

float* aligned_memory=...;
simd::pack<float>* packed_memory = (simd::pack<float>*) aligned_memory;

(this would make my experiment a two-line change)

2. Is there a difference between the allocators in boost/align and what 
simd offers?

Best,
Oswin
