MueLu::RepartitionInterface< LocalOrdinal, GlobalOrdinal, Node > Class Template Reference

Helper class which transforms an "AmalgamatedPartition" array to an unamalgamated "Partition".This is a general class that allows to translate node-based rebalancing information (given by "AmalgamatedPartition") to DOF-based rebalancing information (stored as output in the "Partition" variable). It is meant to be used together with the IsorropiaInterface class which provides the node-based rebalancing information in the "AmalgamatedPartition" variable. It uses the striding information of "A" to transform the amalgamated rebalaning info into DOF-based rebalancing information that can be processed by the RepartitionFactory class. More...

Detailed Description

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

Helper class which transforms an "AmalgamatedPartition" array to an unamalgamated "Partition".

This is a general class that allows to translate node-based rebalancing information (given by "AmalgamatedPartition") to DOF-based rebalancing information (stored as output in the "Partition" variable). It is meant to be used together with the IsorropiaInterface class which provides the node-based rebalancing information in the "AmalgamatedPartition" variable. It uses the striding information of "A" to transform the amalgamated rebalaning info into DOF-based rebalancing information that can be processed by the RepartitionFactory class.

Note
: We assume a constant number of DOFs per node

Input/output of RepartitionInterface

User parameters of RepartitionInterface

Parameter type default master.xml validated requested description
A Factory null * * Generating factory of the matrix A used during the prolongator smoothing process
AmalgamatedPartition Factory null * * Factory generating the AmalgamatedPartition (e.g. an IsorropiaInterface)
number of partitions GO - Short-cut parameter set by RepartitionFactory. Avoid repartitioning algorithms if only one partition is necessary (see details below)

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 RepartitionInterface::GetValidParameters).
The * in the requested column states that the data is requested as input with all dependencies (see RepartitionInterface::DeclareInput).

Variables provided by RepartitionInterface

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

Parameter generated by description
Partition RepartitionInterface 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 underlying Zoltan 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::RepartitionInterface< 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.

template<class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::RepartitionInterface< 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.
