Hyper-Systolic Matrix Multiplication
Thomas Lippert, Nikolay Petkov, Paolo Palazzari +1
A novel parallel algorithm for matrix multiplication is presented. The hyper-systolic algorithm makes use of a one-dimensional processor abstraction. The procedure can be implement…
Multicanonical Hybrid Monte Carlo: Boosting Simulations of Compact QED
G. Arnold, Th. Lippert, K. Schilling
We demonstrate that substantial progress can be achieved in the study of the phase structure of 4-dimensional compact QED by a joint use of hybrid Monte Carlo and multicanonical al…
A Preconditioner for Improved Fermion Actions
N. Eicker, W. Bietenholz, A. Frommer +3
SSOR preconditioning of fermion matrix inversions which is parallelized using a locally-lexicographic lattice sub-division, has been shown to be very efficient for standard Wilson…
Decorrelating Topology with HMC
Th. Lippert, B. Alles, G. Bali +9
The investigation of the decorrelation efficiency of the HMC algorithm with respect to vacuum topology is a prerequisite for trustworthy full QCD simulations, in particular for the…
Hybrid and Orbitally Excited Mesons in Full QCD
P. Lacock, K. Schilling
We present results for the hybrid meson spectrum produced by gluonic excitations in full QCD using Wilson fermions. For the spin-exotic mesons with J^{PC}=1^{-+}, 0^{+-}, and 2^{+-…
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…
