while all page replacement algorithms rely on existence of reference locality to function, a major difference among different replacement algorithms is on how this locality is qualified. lirs uses reuse distance of a page, or the number of distinct pages accessed between two consecutive references of the page, to quantify locality. specifically, lirs uses last and second-to-last references (if any) for this purpose. if a page is accessed for the first time, its reuse distance is infinite. in contrast, lru uses recency of a page, which is the number of distinctive pages accessed after the reference of the page, to quantify locality. to take into account of up-to-date access history, the implementation of lirs actually uses the larger of reuse distance and recency of a page as the metric to quantify its locality, denoted as rd-r. assuming the cache has a capacity of c pages, the lirs algorithm is to rank recently accessed pages according to their rd-r values and retain the c most highly ranked pages in the cache.
