Member Function Documentation

flops()

size_t Kaskade::InverseLocalMatrixStorageBase::flops ( ) const

inline

Reports the number of floating point operations per preconditioner application.

This is a (rather accurate) estimate. Depending on BLAS implementation, lower order contributions may be inaccurate.

Definition at line 80 of file domainDecompositionPreconditioner.hh.

indices()

std::vector< size_t > const & Kaskade::InverseLocalMatrixStorageBase::indices ( ) const

inline

Returns the global degrees of freedom defining the submatrix treated as a block here.

regularize()

template<int m, class LocalMatrix , class Real >

void Kaskade::InverseLocalMatrixStorageBase::regularize ( LocalMatrix &  aloc, Real  r  ) const

Definition at line 90 of file domainDecompositionPreconditioner.hh.

storage()

size_t Kaskade::InverseLocalMatrixStorageBase::storage ( ) const

inline

Reports the storage size (in bytes) of the inverse block matrix.

Minor metadata that does not scale with the matrix size is neglected.
