2+1 Flavor Domain Wall Fermion QCD Lattices: Ensemble Production and (some) Properties

Abstract

The RBC and UKQCD Collaborations continue to produce 2+1 flavor domain wall fermion ensembles, currently focusing on an ensemble with a $96^3\times 192$ volume on SUMMIT at ORNL with $1/a\approx 2.8$ GeV, and smaller ensembles at stronger couplings. The $1/a\approx 2.8$ GeV ensemble uses the Exact One Flavor Algorithm for the strange quark, along with the Multisplitting Preconditioned Conjugate Gradient for solving the Dirac equation. We report on our progress and experience to date with the evolution of this ensemble.
