The Pion-Nucleon sigma-Term with Dynamical Wilson Fermions
SESAM-Collaboration, :, S. Güsken +8
We calculate connected and disconnected contributions to the flavour singlet scalar density amplitude of the nucleon in a full QCD lattice simulation with dynamical Wilson…
Bottomonium from NRQCD with Dynamical Wilson Fermions
A. Spitz, N. Eicker, J. Fingberg +5
We present results for the b \bar b spectrum obtained using an O(M_bv^6)-correct non-relativistic lattice QCD action. Propagators are evaluated on SESAM's three sets of dynamical g…
A Parallel SSOR Preconditioner for Lattice QCD
S. Fischer, A. Frommer, U. Glaessner +7
A parallelizable SSOR preconditioning scheme for Krylov subspace iterative solvers in lattice QCD applications involving Wilson fermions is presented. In actual Hybrid Monte Carlo…
A Parallel SSOR Preconditioner for Lattice QCD
S. Fischer, A. Frommer, U. Glaessner +3
We present a parallelizable SSOR preconditioning scheme for Krylov subspace iterative solvers which proves to be efficient in lattice QCD applications involving Wilson fermions. Ou…
Hyper-Systolic Processing on APE100/Quadrics: N^2-Loop Computations
Th. Lippert, G. Ritzenhöfer, U. Glässner +3
We investigate the performance gains from hyper-systolic implementations of n^2-loop problems on the massively parallel computer Quadrics, exploiting its 3-dimensional interprocess…
