  abstract = {Because many scientific applications require large data
  processing, the importance of parallel I/O has been increasingly recognized.
  For collective I/O, one of the considerable features of parallel I/O, we
  suggest the subgroup method. It is the way of using collective I/O of MPI
  effectively in terms of application programs. From the experimental results,
  we could conclude that the subgroup method for collective I/O is more
  efficient than plain collective I/O.}
