  abstract = {Parallel computers are becoming more powerful and more complex in
  response to the demand for computing power by scientists and engineers.
  Inevitably, new and more complex I/O systems will be developed for these
  systems. In particular we believe that the I/O system must provide the
  programmer with the ability to explicitly manage storage (despite the trend
  toward complex parallel file systems and caching schemes). One method of
  doing so is to have a partitioned secondary storage in which each processor
  owns a logical disk. Along with operating system enhancements which allow
  overheads such as buffer copying to be avoided and libraries to support
  optimal remapping of data, this sort of I/O system meets the needs of high
  performance computing.},
  comment = {They argue that it is important to allow the programmer to
  explicitly control their storage in some way. In particular, they advocate
  the Partitioned Secondary Storage (PSS) model, in which each processor has
  its own logical disk, rather than using a parallel file system (PFS) which
  automatically stripes a linear file across many disks. Basically, programmer
  knows best. Of course, libraries can help. They note that you will often need
  data in a different format than it comes, and may need it output in a
  different format; so, permutation algorithms are needed. Also important to be
  able to overlap computation with I/O. They use LU factorization as an
  example, and give an algorithm. On the nCUBE with the PUMA operating system,
  they get good performance. See womble:pario.}
