http://en.wikipedia.org/wiki/Page_replacement_algorithm#Least_recently_used 之前在网上看到过网友的一个C++实现,感觉不错,所以核心代码就采用了他的设计。相关链接如下: http://www.cppblog.com/red22/articles/62499.html 原作者通过两个MAP对象来记录缓存数据和LRU队列,注意其中的LRU队列并不是按照常用的方...
Over the years many algorithms have been proposed for page replacement. Each algorithm attempts to minimize the page fault rate while incurring minimum overhead. , In this paper we discuses at the traditional algorithms such as LRU. Least Recently Used (LRU) page replacement algorithm is most ...
此外,clock算法还有一系列的变种,参考https://en.wikipedia.org/wiki/Page_replacement_algorithm#cite_note-9 工作集(Working Set) 工作集的意思是,进程在时间段(t - x, t)内使用的内存页集合,也有可能是(t,t+x)所访问的页集合,因此应该将它们尽可能保存在内存中。工作集的实现依赖于OS提供Page Aging的支持。

This article argues that the self-tuning, low-overhead, scan resistant adaptive replacement cache (ARC) algorithm outperforms the least-recently-used (LRU) algorithm by dynamically responding to changing access patterns and continually balancing between workload recency and frequency features. The ARC'...
Although they outperform the traditional LRU policy in performance, they do not consider the access frequency of clean page, which will consequently result in poor I/O performance. In order to solve this problem, we present a new buffering algorithm in this paper, called CCF-LRU, which ...
