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.

void operator() (std::vector< std::pair< const PhantomBlock *, walberla::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!
