Status and Future Perspectives for Lattice Gauge Theory Calculations to the Exascale and Beyond
In this and a set of companion whitepapers, the USQCD Collaboration lays out
a program of science and computing for lattice gauge theory. These whitepapers
describe how calculation using lattice QCD (and other gauge theories) can aid
the interpretation of ongoing and upcoming experiments in particle and nuclear
physics, as well as inspire new ones.Comment: 44 pages. 1 of USQCD whitepapers
Analysis and optimization of weighted ensemble sampling
We give a mathematical framework for weighted ensemble (WE) sampling, a
binning and resampling technique for efficiently computing probabilities in
molecular dynamics. We prove that WE sampling is unbiased in a very general
setting that includes adaptive binning. We show that when WE is used for
stationary calculations in tandem with a coarse model, the coarse model can be
used to optimize the allocation of replicas in the bins.Comment: 22 pages, 3 figure
