Detailed Description

template<class Grid>
class AMDiS::UniqueBorderPartition< Grid >

Determine for each border entity which processor owns it.

All entities must be uniquely owned by exactly one processor, but they can exist on multiple processors. For interior, overlap, and ghost entities the assignment is trivial: interior: owner, otherwise not owner.

For border entities (codim != 0) the ownership is not known a priori and must be communicated. Here we assign the entity to the processor with the lowest rank.

Constructor & Destructor Documentation

UniqueBorderPartition()

UniqueBorderPartition ( int  rank, Grid const &  grid  )

inline

Construct a UniqueBorderPartition DataHandle to be used in a GridView communicator.

Parameters

rank	The own processor rank
idSet	The id set of entity ids to store in borderEntities, typically the grid globalIdSet.

NOTE: Since idSet is stored by reference it must not go out of scope until all calls to gather and scatter are finished.
