Parallel solving only for overlapping grids
Since parallelism on non-overlapping grids currently does not work out (!9), we will only support parallel computations on overlapping grids (YaspGrid, that is) for now. See #6.
Features:
-
parallel solve on YaspGrid with Overlap -
collective HDF5 file reading -
revisited verbosity: only rank 0 writes into std::cout
-
created tests for comparing sequential and parallel output -
extend tests to 3D cases -
remove comments in param_base.hh
regarding processor rank queries -
throw if computation on UG grid is run in parallel -
quick-check if CG
is faster thanBiCGSTAB
(it's not!)
