Detailed Description

Partition connectivity graph into non-overlapping domains using the Zoltan graph partitioning software package. Primarily intended for use in NLDD-based non-linear solves.

Member Typedef Documentation

GlobalCellID

using Opm::ParallelNLDDPartitioningZoltan::GlobalCellID = std::function<int(int)>

Callback type for mapping a vertex/cell ID to a globally unique ID.

ZoltanParamMap

using Opm::ParallelNLDDPartitioningZoltan::ZoltanParamMap = std::map<std::string, std::string>

Collection of parameters to control the partitioning procedure.

Constructor & Destructor Documentation

ParallelNLDDPartitioningZoltan()

Opm::ParallelNLDDPartitioningZoltan::ParallelNLDDPartitioningZoltan ( const Parallel::Communication  comm, const std::size_t  numElements, const GlobalCellID &  globalCell  )

inlineexplicit

Constructor.

Parameters

[in]	comm	MPI communication object. Needed by Zoltan.
[in]	numElements	Number of potential vertices in connectivity graph. Typically the total number of cells on the current rank, i.e., both owned cells and overlap cells.
[in]	globalCell	Callback for mapping (local) vertex IDs to globally unique vertex IDs.

Member Function Documentation

forceSameDomain()

void Opm::ParallelNLDDPartitioningZoltan::forceSameDomain ( std::vector< int > &&  cells )

inline

Force collection of cells to be in same result domain.

Mostly as a means to ensuring wells do not intersect multiple domains/blocks.

Parameters

[in]

cells

Cell collection. Typically those cells which are intersected by a single well.

partitionElements()

std::vector< int > Opm::ParallelNLDDPartitioningZoltan::partitionElements

(

const ZoltanParamMap &

params

)

const

Partition connectivity graph using Zoltan graph partitioning package.

Honours any prescribed requirement that certain cells be placed in a single domain/block.

Parameters

[in]

params

Parameters for Zoltan. Override default settings.

Returns

Partition vector of size numElements. Reachable vertices/cells are partitioned into N blocks numbered 0..N-1. Unreachable vertices get a block ID of -1.

registerConnection()

void Opm::ParallelNLDDPartitioningZoltan::registerConnection ( std::size_t  c1, std::size_t  c2  )

inline

Insert directed graph edge between two vertices.

Parameters

[in]	c1	Source vertex.
	]in]	c2 Sink/destination vertex.
