This is intended mainly for internal use; users should use higher level routines such as <A HREF="../IS/ISLoad.html#ISLoad">ISLoad</A>(), <A HREF="../Vec/VecLoad.html#VecLoad">VecLoad</A>(), <A HREF="../DM/DMLoad.html#DMLoad">DMLoad</A>().
The array is partitioned according to the given <A HREF="../IS/PetscLayout.html#PetscLayout">PetscLayout</A> which is converted to an HDF5 hyperslab.
This name is relative to the current group returned by <A HREF="../Viewer/PetscViewerHDF5OpenGroup.html#PetscViewerHDF5OpenGroup">PetscViewerHDF5OpenGroup</A>().
