Detailed Description

template<typename Adapter>
class Zoltan2::PartitioningSolutionQuality< Adapter >

A class that computes and returns quality metrics.

Todo:

For some problems it will be necessary to build the Model again in order to compute metrics. For now we don't have any problems like that.

write a unit test for this class

Constructor & Destructor Documentation

template<typename Adapter >
Zoltan2::PartitioningSolutionQuality< Adapter >::PartitioningSolutionQuality ( const RCP< const Environment > &  env,
const RCP< const Comm< int > > &  problemComm,
const RCP< const Adapter > &  ia,
const RCP< const PartitioningSolution< Adapter > > &  soln 
)

Constructor.

Parameters:
envthe problem environment
problemCommthe problem communicator
iathe problem input adapter
solnthe solution

The constructor does global communication to compute the metrics. The rest of the methods are local.

Member Function Documentation

template<typename Adapter >
ArrayRCP<const MetricValues<scalar_t> > Zoltan2::PartitioningSolutionQuality< Adapter >::getMetrics ( ) const [inline]

Return the metric values.

Parameters:
valueson return is the array of values.

Definition at line 103 of file Zoltan2_PartitioningSolutionQuality.hpp.

template<typename Adapter >
void Zoltan2::PartitioningSolutionQuality< Adapter >::getObjectCountImbalance ( scalar_t &  imbalance) const [inline]

Return the object count imbalance.

Parameters:
imbalanceon return is the object count imbalance.

Definition at line 110 of file Zoltan2_PartitioningSolutionQuality.hpp.

template<typename Adapter >
void Zoltan2::PartitioningSolutionQuality< Adapter >::getNormedImbalance ( scalar_t &  imbalance) const [inline]

Return the object normed weight imbalance.

Parameters:
imbalanceon return is the object normed weight imbalance. If there were no weights, this is the object count imbalance. If there was one weight, it is the imbalance with respect to that weight.

Definition at line 119 of file Zoltan2_PartitioningSolutionQuality.hpp.

template<typename Adapter >
void Zoltan2::PartitioningSolutionQuality< Adapter >::getWeightImbalance ( scalar_t &  imbalance,
int  idx = 0 
) const [inline]

Return the imbalance for the requested weight.

Parameters:
imbalanceon return is the requested value.
idxis the weight index requested, ranging from zero to one less than the number of weights provided in the input. If there were no weights, this is the object count imbalance.

template<typename Adapter >
void Zoltan2::PartitioningSolutionQuality< Adapter >::printMetrics ( std::ostream &  os) const [inline]

Print all the metrics.
