Optimizing performance per watt on GPUs in High Performance Computing: temperature, frequency and voltage effects
D. C. Price, M. A. Clark, B. R. Barsdell +2
The magnitude of the real-time digital signal processing challenge attached to large radio astronomical antenna arrays motivates use of high performance computing (HPC) systems. Th…
WW Scattering Parameters via Pseudoscalar Phase Shifts
Thomas Appelquist, Ron Babich, Richard C. Brower +15
Using domain-wall lattice simulations, we study pseudoscalar-pseudoscalar scattering in the maximal isospin channel for an SU(3) gauge theory with two and six fermion flavors in th…
Scaling Lattice QCD beyond 100 GPUs
R. Babich, M. A. Clark, B. Joó +3
Over the past five years, graphics processing units (GPUs) have had a transformational effect on numerical lattice quantum chromodynamics (LQCD) calculations in nuclear and particl…
Exploring strange nucleon form factors on the lattice
Ronald Babich, Richard C. Brower, Michael A. Clark +4
We discuss techniques for evaluating sea quark contributions to hadronic form factors on the lattice and apply these to an exploratory calculation of the strange electromagnetic, a…
Multigrid solver for clover fermions
J. C. Osborn, R. Babich, J. Brannick +4
We present an adaptive multigrid Dirac solver developed for Wilson clover fermions which offers order-of-magnitude reductions in solution time compared to conventional Krylov solve…
Parallelizing the QUDA Library for Multi-GPU Calculations in Lattice Quantum Chromodynamics
Ronald Babich, Michael A. Clark, Bálint Joó
Graphics Processing Units (GPUs) are having a transformational effect on numerical lattice quantum chromodynamics (LQCD) calculations of importance in nuclear and particle physics.…
