  abstract = {High-performance computing increasingly occurs on ``computational
  grids'' composed of heterogeneous and geographically distributed systems of
  computers, networks, and storage devices that collectively act as a single
  ``virtual'' computer. A key challenge in this environment is to provide
  efficient access to data distributed across remote data servers. This
  dissertation explores some of the issues associated with I/O for wide-area
  distributed computing and describes an I/O system, called Armada, with the
  following features: a framework to allow application and dataset providers to
  flexibly compose graphs of processing modules that describe the distribution,
  application interfaces, and processing required of the dataset before or
  after computation; an algorithm to restructure application graphs to increase
  parallelism and to improve network performance in a wide-area network; and a
  hierarchical graph-partitioning scheme that deploys components of the
  application graph in a way that is both beneficial to the application and
  sensitive to the administrative policies of the different administrative
  domains. Experiments show that applications using Armada perform well in both
  low- and high-bandwidth environments, and that our approach does an
  exceptional job of hiding the network latency inherent in grid computing.}
