- * 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 explicit parallel file prefix.  See the usage
- * for more detail.
