Detailed Description

template<class LocalSparseMatrixType, class ScalingFactorsViewType, const bool divide>
class Tpetra::Details::LeftScaleLocalCrsMatrix< LocalSparseMatrixType, ScalingFactorsViewType, divide >

Kokkos::parallel_for functor that left-scales a KokkosSparse::CrsMatrix.

Template Parameters

LocalSparseMatrixType	KokkosSparse::CrsMatrix specialization.
ScalingFactorsViewType	Kokkos::View specialization storing scaling factors by which to divide the rows of the local sparse matrix.
divide	If true, divide, else multiply.

Constructor & Destructor Documentation

template<class LocalSparseMatrixType , class ScalingFactorsViewType , const bool divide>

Tpetra::Details::LeftScaleLocalCrsMatrix< LocalSparseMatrixType, ScalingFactorsViewType, divide >::LeftScaleLocalCrsMatrix ( const LocalSparseMatrixType &  A_lcl, const ScalingFactorsViewType &  scalingFactors, const bool  assumeSymmetric  )

inline

Parameters

A_lcl	[in/out] The local sparse matrix.
scalingFactors	[in] rowNorms from EquilibrationInfo.
assumeSymmetric	[in] Whether to assume that the (global) sparse matrix is symmetric. If true, divde matrix entries by square roots of scaling factors; else, divide by the scaling factors themselves.
