2Q 1994 2Q: A Low Overhead High Performance Buffer Management Replacement Algorithm ARC 2003 ARC: A Self-Tuning, Low Overhead Replacement Cache MQ 2001 The Multi-Queue Replacement Algorithm for Second Level B
This article presents a new self-tuning, low overhead algorithm, namely, Adaptive Replacement Cache (ARC). It responds online to changing access patterns, continually balances between the recency and frequency features of the workload, and demonstrates that adaptation eliminates the need for workload...
a. MQ(multi-queue replacement policy MQ ): 参考“The multi-queue replacement algorithm for second level buffer caches” 8. ARC: adaptive replacement cache(IBM), adjusted replacement cache(ZFS) a. 一种自适应,低成本的淘汰算法 b. 它集合了LRU和LFU的优点,并且没有额外的使用和实现成本。 c. 它可...
本文是对《FRD: A Filtering based Buffer Cache Algorithm that Considers both Frequency and Reuse Distance》论文的解构。 LRU 算法在有些 workload 下效果不好(主要是 scan 型以及环形访问,具体就不展开了,感兴趣的参阅论文第一章 "Introduction"),于是人们提出了各种算法(LIRS、ARC 等)来解决此问题。然而还是...
Kao and Lee (2007) propose a cache replacement algorithm for use in a proxy which does transcoding. The transcoding proxy generates different bitrate encodings of the same video and takes into account the byte size and popularity of each encoding when caching (e.g., videos more often access ...
These ghost lists act as scorecards by keeping track of the history of recently evicted cache entries ARC (Adaptive Replacement Cache) [23] utilizes ghost lists (for LRU and LFU) to keep track of the history of recently evicted cache entries and the algorithm dynamically adjusts the size of...
ARC(Adaptive Replacement Cache)是一种结合了LRU和LFU的自适应缓存替换算法,它根据当前的访问模式动态调整缓存空间的大小。 CacheSystem C 支持多种缓存机制的复现,包括LRU、LFU和ARC等。这些机制在实际应用中非常常见,例如在Web服务器、数据库查询优化和文件系统管理等领域都有广泛应用。通过CacheSystem C,开发者可以...

Caching techniques include write-through cache, write-back cache, LRU cache, FIFO cache, random replacement cache, LFU cache, ARC, Belady’s optimal algorithm, and multi-level caching. Each caching technique has its advantages and trade-offs in terms of performance, eviction policies, and memory...
