/*

 * Example of using the parallel HDF5 library to access datasets.

 * Last revised: April 24, 2001.

 *

 * This program contains two parts.  In the first part, the mpi processes

 * collectively create a new parallel HDF5 file and create two fixed

 * dimension datasets in it.  Then each process writes a hyperslab into

 * each dataset in an independent mode.  All processes collectively

 * close the datasets and the file.

 * In the second part, the processes collectively open the created file

 * and the two datasets in it.  Then each process reads a hyperslab from

 * each dataset in an independent mode and prints them out.

 * All processes collectively close the datasets and the file.

 *

 * The need of requirement of parallel file prefix is that in general

 * the current working directory in which compiling is done, is not suitable

 * for parallel I/O and there is no standard pathname for parallel file

 * systems.  In some cases, the parallel file name may even needs some

 * parallel file type prefix such as: "pfs:/GF/...".  Therefore, this

 * example requires an explicite parallel file prefix.  See the usage

 * for more detail.
