Solutions to the coherence, load-balancing and fault-tolerance problems are presented. These solutions have been implemented as a part of PAFS, a parallel/distributed file system, and its performance has been compared to the one achieved by xFS. Using the comparison results, we have observed that the proposed ideas not only solve the main problems of cooperative caches, but also increase the overall system performance. Although the solutions presented in this paper were targeted to a parallel machine, reasonable good results have also been obtained for networks of workstations.}, comment = {They make the claim that it is better not to replicate data into local client caches, rather, it is better to simply make remote read and write requests to the cached block in whatever memory it may be. That reduces the overhead (space and time) of replication and coherency, and leads to better performance. They also present a range of parity-based fault-tolerance mechanisms, and a load-balancing technique that reassigns cache buffers to cache-manager processes.} }
