This project is working to develop new, robust multigrid methods for enabling more complex and higher fidelity physics for lattice quantum chromodynamics (QCD) calculations, and to support their migration into petascale simulations.

Numerical solutions to QCD on a lattice are critical to high-precision experimental tests of the standard model and an ab initio understanding of nuclear matter. The core of these calculations involves inverting a Dirac matrix, which becomes increasingly ill-conditioned as the lattice is refined. Consequently, while terascale computing hardware has exposed this new physics, it is incapable of fully accommodating it.
