摘要：
The combination of a non-overlapping Schwarz preconditioner and the Hybrid Monte Carlo (HMC) algorithm is shown to yield an efficient simulation algorithm for two-flavor lattice QCD with Wilson quarks. Extensive tests are performed, on lattices of size up to 32 x 24(3), with lattice spacings a similar or equal to 0.08 fm and at bare current-quark masses as low as 21 MeV. (C) 2004 Elsevier B.V.
