Hello, I would like to know if anyone knows of a protocol implemented in Ruby with all the cache levels prefetcher modeling. I have been researching this topic and am still trying to find a clear answer. If anyone has any insights or knowledge on this matter, I would greatly appreciate your input. I found that both MESI_Two_Level and MESI_Three_Level have level 1 prefetcher, but I'm curious if there are any ongoing developments to integrate prefetcher to other levels.
