      ENH: Performance improvements for HDF5 writer. · d5ebbc9f
      Kenneth Leiter authored
      Choose dataset name more carefully to avoid querying the file many times.
      Use a more efficient function to check if a dataset already exists in a file.
      Get DSM working with new changes.
      Fix gcc compiler warning in test.

      ENH: Improve performance of hdf5 writes. · decc7dd4
      Kenneth Leiter authored
      Previously, each time a dataset was written to hdf5, the file was opened
      and closed. This was implemented because inside the heavy data writer
      we have no idea whether another dataset will be written, so we don't know
      whether to keep the file open. After profiling large xdmf writes it was
      determined that closing the file appeared to be a bottleneck so hooks were
      added to the heavy data writer to open the file and keep it open while writing.
      This is optional, but was incorporated into several higher level classes
      like XdmfWriter where we know we can leave a file open until we finish writing
      the XML. For our test problem we saw a 7 time performance gain.

      ENH: Add unpartition method to partitioner. · f73576ec
      Kenneth Leiter authored
      Unpartition method takes an XdmfGridCollection of unstructured grids
      and zips them back together into a single XdmfUnstructuredGrid. It uses
      GlobalNodeIds to perform the unpartitioning.
      
      Also added some functionality to the partitioner so that it will properly
      partition set attributes of types other than scalar.

      ENH: Allow arbitrary elements to be partitioned by metis. · 86eefce2
      Kenneth Leiter authored
      The new version of metis uses a different format to supply connectivity
      information to the partitioning algorithm. The new format allows generic
      element types to be passed (as well as mixed topology formats). These changes
      expand the number of element types we can partition in metis (this was tested
      on high-order hexahedron, linear hexahedron, and polyline topologies)

      ENH: Modify documentation for completeness. · 36ed6d02
      Kenneth Leiter authored
      Added documentation to several methods. Modified Doxygen configuration file to
      correctly process macros (tested using Doxygen 1.7.1). Correctly format
      documentation to 80 characters per line.
