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. Image courtesy of DOE/Joanna Griffin.By using multiple grids and separating the modes in the problem onto the various grids most efficiently, the researchers can get through their long line of calculations quicker and easier.
