Sorry for that, but from what I see __builtin_prefetch() just fetches in advance the related pages but it does not guarantee that thy won't be thrown out of the cache. I want to know if there is some way to prefetch and lock some memory unit in cache. I'm pretty sure that there should be a way for this to be done in assembly, but I don't know for C or some gcc built-in
