Accelerating Lattice QCD Multigrid on GPUs Using Fine-Grained Parallelization
M. A. Clark, Bálint Joó, Alexei Strelchenko +3
The past decade has witnessed a dramatic acceleration of lattice quantum chromodynamics calculations in nuclear and particle physics. This has been due to both significant progress…
Algorithms for Disconnected Diagrams in Lattice QCD
Arjun Singh Gambhir, Andreas Stathopoulos, Kostas Orginos +3
Computing disconnected diagrams in Lattice QCD (operator insertion in a quark loop) entails the computationally demanding problem of taking the trace of the all to all quark propag…
Deflation as a Method of Variance Reduction for Estimating the Trace of a Matrix Inverse
Arjun Singh Gambhir, Andreas Stathopoulos, Kostas Orginos
Many fields require computing the trace of the inverse of a large, sparse matrix. The typical method used for such computations is the Hutchinson method which is a Monte Carlo (MC)…
