Detailed Description

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

Interface to Isorropia.

Interface to Isorropia allowing to access other rebalancing/repartitioning algorithms from Zoltan than RCB This includes methods (like PHG) which do not rely on user-provided coordinate or mesh information. This class produces node-based rebalancing information (stored in "AmalgamatedPartition") which is used as input for the RepartitionInterface class.

It tries to consider the "number of partitions" variable when repartitioning the system.

Note
Only works with the Epetra stack in Xpetra

Input/output of IsorropiaInterface

User parameters of IsorropiaInterface

Parameter type default master.xml validated requested description
A Factory null * * Generating factory of the matrix A used during the prolongator smoothing process
UnAmalgamationInfo Factory null * * Generating factory of UnAmalgamationInfo
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 IsorropiaInterface::GetValidParameterList).
The * in the requested column states that the data is requested as input with all dependencies (see IsorropiaInterface::DeclareInput).

Variables provided by IsorropiaInterface

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

Parameter generated by description
AmalgamatedPartition IsorropiaInterface GOVector based on the node map associated with the graph of A

Member Function Documentation

◆ GetValidParameterList()

template<class LocalOrdinal , class GlobalOrdinal , class Node >
RCP< const ParameterList > MueLu::IsorropiaInterface< 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.

Reimplemented from MueLu::Factory.

Definition at line 47 of file MueLu_IsorropiaInterface_def.hpp.

◆ DeclareInput()

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

Definition at line 59 of file MueLu_IsorropiaInterface_def.hpp.

◆ Build()

template<class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::IsorropiaInterface< LocalOrdinal, GlobalOrdinal, Node >::Build ( Level currentLevel) const
virtual

Build an object with this factory.

Implements MueLu::SingleLevelFactoryBase.
