Detailed Description

template<typename gauge_field, typename DIRAC_OP>
class Hasenbusch_action_2< gauge_field, DIRAC_OP >

The second Hasenbusch action term, D_h2 = D/(D^dagger + mh). The force and action of the second term are significantly different from the standard fermion action and are implemented here.

initial_guess()

template<typename gauge_field , typename DIRAC_OP >

void Hasenbusch_action_2< gauge_field, DIRAC_OP >::initial_guess ( Field< vector_type > &  chi, Field< vector_type > &  psi  )

inline

Build an initial guess for the fermion matrix inversion by inverting first in the limited space of a few previous solutions. These are saved in old_chi.
