Description

In the current implementation of the parallel interface in dune-grid there are several things missing:

  1. Communication of data through Intersections. The current interface would not allow parallel grids with non-conforming refinement without ghost cells or overlap. However, is is required for efficient implementation of DG methods on super computers with a large number of cores and only a few number of cells per core.
  2. Non-blocking communication or even asynchronous communication is currently not possible with communication methods on the Grid class.

Please add further things missing such that we obtain a list of possible improvements for the next meeting.
