Conclusions• It is important to share the cache efficiently in CMPs• LRU does not achieve optimal sharing of the cache• Cache partitioning can alleviate its consequences• ABFCP– shows increasing promise as the number of cores increase– provides better performance than LRU at a reasonable cost(5.5% increase for an 8-core system achieves similar results tousing LRU with a 50% bigger L2 cache)
