Interesting. The BLIS implementation prefetches only the first cache
line, before traversing a given interval of memory. This clearly
confirms the implementation relies on hardware preteching to prefetch
the subsequent lines. This makes a lot of sense. Yet surprisingly, the
BLIS implementation does not attempt at anticipating the fetch. It
schedules the prefetch instruction right before the first load of a
given interval.
