  abstract = {Performance of I/O intensive applications on a multiprocessor
  system depends mostly on the variety of disk access delays encountered in the
  I/O system. Over the years, the improvement in disk performance has taken
  place more slowly than the corresponding increase in processor speeds. It is
  therefore necessary to model I/O delays and evaluate performance benefits of
  moving an application to a better multiprocessor system. We perform such an
  analysis by measuring I/O delays for a synthesized application that uses a
  parallel distributed file system. The aim of this study is to evaluate the
  performance benefits of better disks in a multiprocessor system. We report on
  how the I/O performance would be affected if an application were to run on a
  system which would have better disks and communication links. In this study,
  we show a substantial improvement in the performance of an I/O system with
  better disks and communication links with respect to the existing system.}
