The parallel component responsible for managing the DG elements that compose the computational domain.
This parallel component will perform the actions specified by the PhaseDepActionList.
The element assignment to processors is performed by domain::BlockZCurveProcDistribution (using a Morton space-filling curve), unless static constexpr bool use_z_order_distribution = false; is specified in the Metavariables, in which case elements are assigned to processors via round-robin assignment. In both cases, an unordered set of size_ts can be passed to the allocate_array function which represents physical processors to avoid placing elements on. If the space-filling curve is used, then if static constexpr bool local_time_stepping = true; is specified in the Metavariables, Elements will be distributed according to their computational costs determined by the number of grid points and minimum grid spacing of that Element (see domain::get_num_points_and_grid_spacing_cost()), else the computational cost is determined only by the number of grid points in the Element.
