Adaptive multigrid algorithm for the lattice Wilson-Dirac operator.
We present an adaptive multigrid solver for application to the non-Hermitian Wilson-Dirac system of QCD. The key components leading to the success of our proposed algorithm are the use of an adaptive projection onto coarse grids that preserves the near null space of the system matrix together with a simplified form of the correction based on the so-called γ5-Hermitian symmetry of the Dirac oper...

متن کاملSchwarz-preconditioned HMC algorithm for two-flavour lattice QCD
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-flavour lattice QCD with Wilson quarks. Extensive tests are performed, on lattices of size up to 32×24, with lattice spacings a ≃ 0.08 fm and at bare current-quark masses as low as 21MeV.
متن کاملRecent algorithm and machine developments for lattice QCD
I review recent machine trends and algorithmic developments for dynamical lattice QCD simulations with the HMC algorithm for Wilson-type fermions. The topics include the trend toward multi-core processors and general purpose GPU (GPGPU) computing, and improvements on the quark determinant preconditioning, molecular dynamics integrator, and quark solvers. I also discuss the prospect on the use o...
متن کاملOdd-flavor Hybrid Monte Carlo Algorithm for Lattice QCD
We discuss hybrid Monte Carlo algorithms for odd-flavor lattice QCD simulations. The algorithms include a polynomial approximation which enables us to simulate odd-flavor QCD in the framework of the hybrid Monte Carlo algorithm. In order to make the algorithms exact, the correction factor to the polynomial approximation is also included in an economical, stochastic way. We test the algorithms f...
