· Phys. Rev. D; (United States)
Preconditioning has been successfully used to accelerate theconjugate-gradient algorithm for inverting the lattice Dirac operator in theWilson formulation. However, technical problems have arisen when trying toapply it in the Kogut-Susskind formulation. We discuss attempts to circumventthe technical problems and to find a successful way to precondition theKogut-Susskind fermion matrix.
