  abstract = {For a high-performance parallel machine to be a scalable system,
  it must also have a scalable parallel I/O system. Recently, several
  commercial machines (e.g. Intel Touchstone Delta, Paragon, CM-5, Ncube-2)
  have been built that provide features for parallel I/O. However, very little
  is understood about the performance of these I/O systems. This paper presents
  an experimental evaluation of the Intel Touchstone Delta's Concurrent File
  System (CFS). The CFS utilizes the declustering of large files across the
  disks to improve the I/O performance. Data files can be read or written on
  the CFS using 4 access modes. \par We present performance measurements for
  the CFS on the Touchstone Delta with 512 compute nodes and 32 I/O nodes. The
  study focuses on file read/write rates for various configurations of I/O and
  compute nodes. The study attempts to show the effect of access modes, buffer
  sizes and volume restrictions on the system performance. The paper also shows
  that the performance of the CFS can greatly vary for various data
  distributions commonly employed in scientific and engineering applications.},
