Factory for building permutation matrix that can be be used to shuffle data (matrices, vectors) among processes.
This factory acts on both the number of partitions and a vector (usually created by Zoltan) that indicates to which partitions the current level's system matrix's DOFS belong.
We always call the Interface routines in ZoltanInterface, Zoltan2Interface or IsorropiaInterface, but they have special short-cuts if no rebalancing is necessary (then return "Partition = null") or all data is moved to one processor.
| Parameter | type | default | master.xml | validated | requested | description |
|---|---|---|---|---|---|---|
| A | Factory | null | * | * | Generating factory of the matrix A used during the prolongator smoothing process | |
| number of partitions | Factory | null | * | * | Factory calculating the "number of partitions" for rebalancing (usually an instance of RepartitionHeuristicFactory) | |
| Partition | Factory | null | * | * | Factory generating the "Partition" variable containing the distribution of the DOFs over the reduced number of processors (given by "number of partitions") | |
| repartition: print partition distribution | bool | false | * | * | Partition distribution printout. | |
| repartition: remap parts | bool | false | * | * | Postprocessing for partitioning to reduce data migration. | |
| repartition: remap num values | int | 4 | * | * | Number of maximum components from each processor used to construct partial bipartite graph. |
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 RepartitionFactory::GetValidParameters).
The * in the requested column states that the data is requested as input with all dependencies (see RepartitionFactory::DeclareInput).
After RepartitionFactory::Build the following data is available (if requested)
| Parameter | generated by | description |
|---|---|---|
| Importer | RepartitionFactory | Importer used for rebalancing |
Importer contains the Xpetra::Import object to rebalance the data (matrix or vectors). It is Teuchos::null if no rebalancing is necessary.

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

If 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.

Determine which process should own each partition.
Partitions are assigned to processes in order to minimize data movement. The basic idea is that a good choice for partition owner is to choose the pid that already has the greatest number of nonzeros for a particular partition. If willAcceptPartition=false is set on a rank, no partition will be placed there.
