This paper is concerned with online cachingalgorithms 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).
