在线伴侣缓存

Online Companion Caching

Manor Mendel, Steven S. Seiden

摘要:

本文关注的是在线缓存算法的(n,k)-同伴缓存,定义的Brehob等。在该模型中,高速缓存由两个组件组成:k路组关联高速缓存和大小为n的同伴全关联高速缓存。证明了该问题的确定竞争比为(n+1)(k+1)-1,随机竞争比为O(\log n \log k)和Ω(\log n + \log k).

英文摘要:

This paper is concerned with online caching algorithms for the (n,k)-companion cache, defined by Brehob et. al. In this model the cache is composed of two components: a k-way set-associative cache and a companion fully-associative cache of size n. We show that the deterministic competitive ratio for this problem is (n+1)(k+1)-1, and the randomized competitive ratio is O(\log n \log k) and Ω(\log n +\log k).
