Lattice QCD has been turning a corner in the last couple of years since the time of LeptonPhoton 2007 . Previously, despite the premise, it remained an approximate method requiring extrapolations… (More)
Abstract This is a transcript of the recorded panel discussion on the cost of dynamical quark simulations at Lattice2001.
The authors have developed a hybrid computing system called HMCS-G, a Grid-enabled Heterogeneous Multi-Computer System, that provides a multiple cluster environment centered around a dedicated… (More)
Both the scientific community and the general public have expressed concern over scientific misconduct. The number of retracted articles has increased dramatically over the past 20 years and now… (More)
We discuss the physics and computation of lattice QCD, a space-time lattice formulation of quantum chromodynamics, and Kenneth Wilson’s seminal role in its development. We start with the fundamental… (More)
Abstract We report on coding and performance of our polynomial hybrid Monte Carlo program on the Earth Simulator. At present the entire program achieves 25-40% efficiency. An analysis of overheads… (More)
A brief review is given of the current status and near‐future prospect of lattice QCD studies of the Standard Model. After summarizing a bit of history, we describe current attempts toward inclusion… (More)
A brief review is given of the lattice QCD calculation of the hadron spectrum. The status of current attempts toward inclusion of dynamical up, down and strange quarks is summarized focusing on our… (More)
