distributeFieldPartitions()

std::shared_ptr<PanNDE::Array<std::shared_ptr<PanNDE::Field> > > NetMPI::MetisPartitioner::distributeFieldPartitions ( std::shared_ptr< PanNDE::Array< int >>  partitionIds, std::shared_ptr< PanNDE::FieldFactory >  maker, std::shared_ptr< PanNDE::Field >  global_field = nullptr, int  field_source_rank = 0  )

inlineoverridevirtual

distribute a field

Parameters

partitionIds	which partitions the local process is requesting
maker	the field factory
global_field	the field that must be partitioned that is currently on the field_source_rank process
field_source_rank	process which has the global field and is distributing the field partitions

Implements Controller::Partitioner.

inlineoverridevirtual

distribute the mesh

Parameters

partitionIds	which partitions the local process is requesting
maker	the mesh factory
mesh_source_rank	process which has the global mesh and is distributing the mesh partitions

Implements Controller::Partitioner.

partitionMesh()

inlineoverridevirtual

partition a mesh

Parameters

Nparts	number of parts to decompose the mesh into
global_mesh	the monolithic mesh to partition

Implements Controller::Partitioner.
