  abstract = {We present the results of an experimental evaluation of the
  parallel I/O systems of the IBM SP and Intel Paragon using a real
  three-dimensional parallel application code. This application, developed by
  scientists at the University of Chicago, simulates the gravitational collapse
  of self-gravitating gaseous clouds. It performs parallel I/O by using library
  routines that we developed and optimized separately for the SP and Paragon.
  The I/O routines perform two-phase I/O and use the parallel file systems
  PIOFS on the SP and PFS on the Paragon. We studied the I/O performance for
  two different sizes of the application. In the small case, we found that I/O
  was much faster on the SP. In the large case, open, close, and read
  operations were only slightly faster, and seeks were significantly faster, on
  the SP; whereas, writes were slightly faster on the Paragon. The
  communication required within our I/O routines was faster on the Paragon in
  both cases. The highest read bandwidth obtained was 48\,Mbytes/sec., and the
  highest write bandwidth obtained was 31.6\,Mbytes/sec., both on the SP.}
