  abstract = {In order for I/O systems to achieve high performance in a
  parallel environment, they must either sacrifice client-side file caching, or
  keep caching and deal with complex coherency issues. The most common
  technique for dealing with cache coherency in multi-client file caching
  environments uses file locks to bypass the client-side cache. Aside from
  effectively disabling cache usage, file locking is sometimes unavailable on
  larger systems. \par The high-level abstraction layer of MPI allows us to
  tackle cache coherency with additional information and coordination without
  using file locks. By approaching the cache coherency issue further up, the
  underlying I/O accesses can be modified in such a way as to ensure access to
  coherent data while satisfying the user's I/O request. We can effectively
  exploit the benefits of a file system's client-side cache while minimizing
  its management costs.}
