  abstract = {In this paper we present PAFS, a new parallel/distributed file
  system. Within the whole file system, special interest is placed on the
  caching and prefetching mechanisms. We present a cooperative cache that
  avoids the coherence problem while it continues to be highly scalable and
  achieves very good performance. We also present an aggressive prefetching
  algorithm that allows full utilization of the big caches offered by the
  cooperative cache mechanism. All the results presented in this paper have
  obtained through simulation using the Sprite workload.},
