Query: Solution of the Dirac equation in lattice QCD using a domain
  decomposition method   Efficient algorithms for the solution of partial differential equations on
parallel computers are often based on domain decomposition methods. Schwarz
preconditioners combined with standard Krylov space solvers are widely used in
this context, and such a combination is shown here to perform very well in the
case of the Wilson--Dirac equation in lattice QCD. In particular, with respect
to even-odd preconditioned solvers, the communication overhead is significantly
reduced, which allows the computational work to be distributed over a large
number of processors with only small parallelization losses.
