Multigrid Rendering (IMAGE) DOE/Oak Ridge National Laboratory Caption This image shows an artist's depiction of the team's QCD multigrid method. The top image is fine-grid, which allows the team to simulate high-frequency noise of a proton simulation. The bottom image represents the coarse grid, which supports low-energy, long-distance modes that slow down solvers.
