walberla::blockforest::MetisAssignmentFunctor Class Reference

Detailed Description

Assignment functor for ParMetis based load balancing.

Uses BlockInfo::computationalWeight as vertex weight. Uses the overlap between neighboring domains as edge weight.

#include <MetisAssignmentFunctor.h>

Public Types
using	PhantomBlockWeight = blockforest::DynamicParMetisBlockInfo
	Convenience typedef to be used as PhantomBlock weight in conjunction with this weight assignment functor.
using	PhantomBlockWeightPackUnpackFunctor = blockforest::DynamicParMetisBlockInfoPackUnpack
	Convenience typedef for pack and unpack functions to be used in conjunction with PhantomBlockWeight.

Public Member Functions
	MetisAssignmentFunctor (shared_ptr< blockforest::InfoCollection > &ic, const real_t baseWeight=10.0_r)
void	operator() (std::vector< std::pair< const PhantomBlock *, std::any > > &blockData, const PhantomBlockForest &forest)
void	setBaseWeight (const double weight)
double	getBaseWeight () const

Private Attributes
shared_ptr< blockforest::InfoCollection >	ic_
double	baseWeight_ = 10.0
	Base weight due to allocated data structures. A weight of zero for blocks is dangerous as empty blocks might accumulate on one process!
