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.
