Continuing Progress on a Lattice QCD Software Infrastructure

Data Envelopment Analysis from simulation on the Lattice QCD using CCR model

One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...

National Computational Infrastructure for Lattice Gauge Theory: Accomplishments and Opportunities Lattice QCD Executive Committee

The objective of the SciDAC Project National Computational Infrastructure for Lattice Gauge Theory is to construct the computational infrastructure needed to study quantum chromodynamics (QCD), the fundamental theory of the strong forces of subatomic physics. Nearly all high energy and nuclear physicists in the United States working on the numerical study of QCD are involved in this project, an...

Lattice QCD with Commodity Hardware and Software

Large scale QCD Monte Carlo calculations have typically been performed on either commercial supercomputers or specially built massively parallel computers such as Fermilab’s ACPMAPS. Commodity computer systems offer impressive floating point performance-tocost ratios which exceed those of commercial supercomputers. As high performance networking components approach commodity pricing, it becomes...

Heavy Quarks on the Lattice

I review the basic ideas behind lattice QCD calculations that involve charm and bottom quarks. I report on the progress in getting the correct hyperfine splitting in charmonium from lattice QCD. Some of the basic technology behind numerical lattice QCD calculations is explained by studying some specific examples: computation of the charm quark mass, and the calculation of fB .
