Caches are used to store a subset of a larger memory space in a smaller, faster memory, with the hope that future memory accesses will find their data in the cache. Traditionally, caches have used (approximations of) the least-recently used (LRU) replacement policy, but LRU performs poorly with cyclic access patterns with working sets larger than the cache. Intel Ivy Bridge’s L3 cache uses an improved adaptive replacement policy, and is no longer purely pseudo-LRU . . . → Read More: Intel Ivy Bridge Cache Replacement Policy
