  abstract = {Caching and prefetching are important mechanisms for speeding up
  access time to data on secondary storage. Recent work in competitive online
  algorithms has uncovered several promising new algorithms for caching. In
  this paper, we apply a form of the competitive philosophy for the first time
  to the problem of prefetching to develop an optimal universal prefetcher in
  terms of fault ratio, with particular applications to large-scale databases
  and hypertext systems. Our algorithms for prefetching are novel in that they
  are based on data compression techniques that are both theoretically optimal
  and good in practice. Intuitively, in order to compress data effectively, you
  have to be able to predict future data well, and thus good data compressors
  should be able to predict well for purposes of prefetching. We show for
  powerful models such as Markov sources and $m$th order Markov sources that
  the page fault rates incurred by our prefetching algorithms are optimal in
  the limit for almost all sequences of page accesses.},
  comment = {``This... is on prefetching, but I think the ideas will have a lot
  of use with parallel disks. The implementations we have now are doing
  amazingly well compared to LRU.'' [Vitter]. See vitter:jprefetch.}
