Member Function Documentation

coarsen()

Graph::VertexDescriptor Dune::Amg::ParallelIndicesCoarsener< OwnerOverlapCopyCommunication< G, L >, E >::coarsen ( ParallelInformation & fineInfo, Graph & fineGraph, VM & visitedMap, AggregatesMap< typename Graph::VertexDescriptor > & aggregates, ParallelInformation & coarseInfo, typename Graph::VertexDescriptor noAggregates, bool useFixedOrder = false )

inlinestaticinherited

Build the coarse index set after the aggregatio.

Parameters

fineInfo	The parallel information at the fine level.
fineGraph	The graph of the fine lecel,
visitedMap	Map for marking vertices as visited.
aggregates	The mapping of unknowns onto aggregates.
coarseInfo	The information about the parallel data decomposition on the coarse level.
noAggregates
useFixedOrder	Flag indicating if creating indices for the coarser level should be done in a fixed order, i.e., the order in which the rows were sent. If set to true, this makes the runs reproducible but it might slow down performance.

Returns

The number of unknowns on the coarse level.
