  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.
