Improving HISQ propagator solves using deflation
Leon Hostetler, M. A. Clark, Carleton DeTar +2
Typically, the conjugate gradient (CG) algorithm employs mixed precision and even-odd preconditioning to compute propagators for highly improved staggered quarks (HISQ). This appro…
Multigrid for Staggered Lattice Fermions
Richard C. Brower, M. A. Clark, Alexei Strelchenko +1
Critical slowing down in Krylov methods for the Dirac operator presents a major obstacle to further advances in lattice field theory as it approaches the continuum solution. Here w…
QCD on GPUs: cost effective supercomputing
M. A. Clark
The exponential growth of floating point power in graphics processing units (GPUs), together with their low cost, has given rise to an attractive platform upon which to deploy latt…
Toward TeV Conformality
Thomas Appelquist, Adam Avakian, Ron Babich +11
We study the chiral condensate for an SU(3) gauge theory with massless Dirac fermions in the fundamental representation when is increased from 2 to 6. For $…
