Online Hierarchical Cooperative Caching ∗ Theory of Computing Systems (2008)
Xiaozhou Li, C. Greg Plaxton, Mitul Tiwari, Arun Venkataramani
Abstract. We address a hierarchical generalization of the well-known disk paging problem. In the hierarchical cooperative caching problem, a set of n machines residing in an ultrametric space...
