  abstract = {We present a fundamental improvement of the generic techniques
  for non-contiguous file access in MPI-IO. The improvement consists in the
  replacement of the conventional data management algorithms based on a
  representation of the non-contiguous fileview as a list of (offset, length)
  tuples. The improvement is termed listless i/o as it instead makes use of
  space- and time-efficient datatype handling functionality that is completely
  free of lists for processing non-contiguous data in the file or in memory.
  Listless i/o has been implemented for both independent and collective file
  accesses and improves access performance by increasing the data throughput
  between user buffers and file buffers. Additionally, it reduces the memory
  footprint of the process performing non-contiguous I/O. In this paper we give
  results for a synthetic benchmark on a PC cluster using different file
  systems. We demonstrate improvements in I/O bandwidth that exceed a factor of
  10.},
