  comment = {Derives formulas for the speedup with and without I/O considered
  and with parallel software and hardware format conversion. Considering I/O
  gives a more optimistic view of the speedup of a program {\em assuming} that
  the parallel version can use its I/O bandwidth as effectively as the serial
  processor. Concludes that, for a given number of processors, increasing the
  I/O bandwidth is the most effective way to speed up the program (over the
  format conversion improvements).}
