  abstract = {This paper focuses on extending the power of caching and
  prefetching to reduce file read latencies by exploiting application level
  hints about future I/O accesses. We argue that systems that disclose
  high-level knowledge can transfer optimization information across module
  boundaries in a manner consistent with sound software engineering principles.
  Such Transparent Informed Prefetching (TIP) systems provide a technique for
  converting the high throughput of new technologies such as disk arrays and
  log-structured file systems into low latency for applications. Our
  preliminary experiments show that even without a high-throughput I/O
  sub-system TIP yields reduced execution time of up to 30\% for applications
  obtaining data from a remote file server and up to 13\% for applications
  obtaining data from a single local disk. These experiments indicate that
  greater performance benefits will be available when TIP is integrated with
  low level resource management policies and highly parallel I/O subsystems
  such as disk arrays.},
