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