Possibilities for extensions

+ +The program keeps a complete copy of the Triangulation and DoFHandler objects +on every processor. That's obviously the bottleneck for as far as +parallelization goes. Internally, within deal.II, parallelizing the data +structures used in hierarchic and unstructured triangulations is a very hard +problem, and it took us a few more years to make this happen. The step-40 +tutorial program and the @ref distributed documentation module talk about how +to do these steps and what it takes from an application perspective.
