Description

The RBC and UKQCD Collaborations have used 2+1 flavor Domain Wall Fermion ensembles, generated with the Iwasaki gauge action plus the Dislocation Suppressing Determinant Ratio (DSDR), for a variety of calculations, including our ongoing G-parity calculation of $K \to \pi \pi$ matrix elements. These calculations have been done with 1/a = 1.35 GeV. With the HotQCD Collaboration, zero and finite temperature ensembles at even coarser lattice spacings, 1/a = 1 GeV, have been produced. These coarse, zero temperature ensembles have been included in global fits for light hadronic observables and show scaling errors of a few percent for them. Large physical volume ensembles at 1/a = 1 GeV are being generated for a variety of measurements and our ongoing investigation of their properties will be presented.
