Constructor & Destructor Documentation

MultiCommGatherScatter()

template<typename GFS , typename RankIndex , typename V >

Dune::PDELab::MultiCommGatherScatter< GFS, RankIndex, V >::MultiCommGatherScatter ( const GFS &  gfs, RankIndex  rank, std::vector< std::shared_ptr< V > >  target_vectors, std::vector< RankIndex >  neighbor_ranks  )

inline

Parameters

gfs	Grid function space to be operated on.
rank	The MPI rank of the current process.
target_vectors	Vectors which the received vectors will be written to.
neighbor_ranks	List of ranks of neighboring subdomains defining the order in which results are written to target_vectors.
