  abstract = {A majority of parallel applications obtain parallelism by
  partitioning data over multiple processors. Accessing distributed data
  structures like arrays from files often requires each processor to make a
  large number of small non-contiguous data requests. This problem can be
  addressed by replacing small non-contiguous requests by large collective
  requests. This approach, known as Collective I/O, has been found to work
  extremely well in practice. In this paper, we describe implementation and
  evaluation of a collective I/O prototype in a production parallel file system
  on the Intel Paragon. The prototype is implemented in the PFS subsystem of
  the Intel Paragon Operating System. We evaluate the collective I/O
  performance using its comparison with the PFS M_RECORD and M_UNIX I/O modes.
  It is observed that collective I/O provides significant performance
  improvement over accesses in M_UNIX mode. However, in many cases, various
  implementation overheads cause collective I/O to provide lower performance
  than the M_RECORD I/O mode.},
