Detailed Description

template<class Scalar, class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::NodePartitionInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Partitioning within a node only

This interface provides partitioning within a node.

Input/output of NodePartitionInterface

User parameters of NodePartitionInterface

Parameter	type	default	validated	requested	description
A	Factory	null	*	*	Generating factory of the matrix A used during the prolongator smoothing process
Coordinates	Factory	null	*	(*)	Factory generating coordinates vector used for rebalancing. The coordinates are only needed when the chosen algorithm is 'multijagged' or 'rcb'.
ParameterList	ParamterList	null	*		NodePartition parameters
number of partitions	GO	-			Short-cut parameter set by RepartitionFactory. Avoid repartitioning algorithms if only one partition is necessary (see details below)
NodeComm	Factory	null	*	(*)	Factory generating NodeComm.

The * in the master.xml column denotes that the parameter is defined in the master.xml file.
The * in the validated column means that the parameter is declared in the list of valid input parameters (see NodePartitionInterface::GetValidParameters).
The * in the requested column states that the data is requested as input with all dependencies (see NodePartitionInterface::DeclareInput).

Variables provided by NodePartitionInterface

After NodePartitionInterface::Build the following data is available (if requested)

Parameter	generated by	description
Partition	NodePartitionInterface	GOVector based on the Row map of A (DOF-based) containing the process id the DOF should be living in after rebalancing/repartitioning

The "Partition" vector is used as input for the RepartitionFactory class. If Re-partitioning/rebalancing is necessary it uses the "Partition" variable to create the corresponding Xpetra::Import object which then is used by the RebalanceFactory classes (e.g., RebalanceAcFactory, RebalanceTransferFactory,...) to rebalance the coarse level operators.

The RepartitionHeuristicFactory calculates how many partitions are to be built when performing rebalancing. It stores the result in the "number of partitions" variable on the current level (type = GO). If it is "number of partitions=1" we skip the NodePartition call and just create an dummy "Partition" vector containing zeros only. If no repartitioning is necessary (i.e., just keep the current partitioning) we return "Partition = Teuchos::null". If "number of partitions" > 1, the algorithm tries to find the requested number of partitions.

RCP< const ParameterList > MueLu::NodePartitionInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >::GetValidParameterList ( ) const

virtual

Return a const parameter list of valid parameters that setParameterList() will accept.

Also define the default values of parameters according to the input parameter list.

Implements MueLu::ParameterListAcceptor.

void MueLu::NodePartitionInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >::DeclareInput ( Level & currentLevel ) const

virtual

Specifies the data that this class needs, and the factories that generate that data.

If the Build method of this class requires some data, but the generating factory is not specified in DeclareInput, then this class will fall back to the settings in FactoryManager.

Implements MueLu::SingleLevelFactoryBase.
