  abstract = {I/O performance remains a weakness of parallel computing systems
  today. While this weakness is partly attributed to rapid advances in other
  system components, I/O interfaces available to programmers and the I/O
  methods supported by file systems have traditionally not matched efficiently
  with the types of I/O operations that scientific applications perform,
  particularly noncontiguous accesses. The MPI-IO interface allows for rich
  descriptions of the I/O patterns desired for scientific applications and
  implementations such as ROMIO have taken advantage of this ability while
  remaining limited by underlying file system methods. \par A method of
  noncontiguous data access, list I/O, was recently implemented in the Parallel
  Virtual File System (PVFS). We implement support for this interface in the
  ROMIO MPI-IO implementation. Through a suite of non-contiguous I/O tests we
  compared ROMIO list I/O to current methods of ROMIO noncontiguous access and
  found that the list I/O interface provides performance benefits in many
  noncontiguous cases.}
