Detailed Description
template<typename T>
class Chroma::MultiSystemSolver< T >
Linear multi-system solvers.
Solves multi-shift linear systems of equations. The solver may only live on a subset.

Member Function Documentation
◆ operator()()
|
pure virtual |
Apply the operator onto a source std::vector.
Solves A*psi = chi or psi = A^(-1)*chi up to some accuracy. There is the interesting possibility of generalizing to support PLUS/MINUS
Should the accuracy be specified here ???
Should the shifts be here or in the constructor???
Implemented in Chroma::MdagMMultiSysSolverCGChronoClover, Chroma::MdagMMultiSysSolverCG< T >, and Chroma::LinOpMultiSysSolverMR< T >.
◆ subset()
|
pure virtual |
Return the subset on which the operator acts.
Implemented in Chroma::MdagMMultiSysSolverCGChronoClover, Chroma::MdagMMultiSysSolverCG< T >, and Chroma::LinOpMultiSysSolverMR< T >.
