Strange quark content of the nucleon
Ronald Babich, Richard Brower, Michael Clark +3
We discuss the calculation of disconnected diagrams needed for determining the strange quark content of the nucleon on the lattice. We present results for the strange scalar form f…
Blasting through lattice calculations using CUDA
Kipton Barros, Ronald Babich, Richard Brower +2
Modern graphics hardware is designed for highly parallel numerical tasks and provides significant cost and performance benefits. Graphics hardware vendors are now making available…
Adaptive Multigrid Algorithm for the QCD Dirac-Wilson Operator
J. Brannick, R. C. Brower, M. A. Clark +2
We present a new multigrid solver that is suitable for the Dirac operator in the presence of disordered gauge fields. The key behind the success of the algorithm is an adaptive pro…
The Rational Hybrid Monte Carlo Algorithm
M. A. Clark
The past few years have seen considerable progress in algorithmic development for the generation of gauge fields including the effects of dynamical fermions. The Rational Hybrid Mo…
Accelerating Staggered Fermion Dynamics with the Rational Hybrid Monte Carlo (RHMC) Algorithm
M. A. Clark, A. D. Kennedy
Improved staggered fermion formulations are a popular choice for lattice QCD calculations. Historically, the algorithm used for such calculations has been the inexact R algorithm,…
Testing Algorithms for Finite Temperature Lattice QCD
M. Cheng, M. A. Clark, C. Jung +1
We discuss recent algorithmic improvements in simulating finite temperature QCD on a lattice. In particular, the Rational Hybrid Monte Carlo(RHMC) algorithm is employed to generate…
