Abstract
We present preliminary results on the scattering of pseudoscalar, vector, and scalar mesons on a physical pion mass, 2+1 flavor mobius-DWF, ensemble with periodic boundary conditions (PBCs) generated by the RBC and UKQCD collaborations. Using all-to-all propagators, we produce thousands of correlator momentum combinations. Energy spectra and phase shifts, including excited states, are then extracted via the solutions of a generalized eigenvalue problem. Included in this talk will also be an overview of the computational strategies employed, including a discussion of split-CG matrix solvers (communication avoidance) and lattice crossing symmetry (momentum combinatorics reduction). These studies are intended to serve as groundwork for a full PBC calculation of direct CP violation in K->pipi later this year.
