The computational cost of fluid simulations grows rapidly with grid resolution. With the recent slowdown of Moore's Law, it can take many decades for 10x higher resolution grids to become affordable. To break this major barrier in highperformance scientific computing, we used a datadriven approach to learn an optimal numerical solver that can retain highaccuracy at much coarser grids. We applied this method to 2D turbulent advection and achieved 4x effective resolution than traditional highorder fluxlimited advection solvers. The machine learning component is tightly integrated with traditional finitevolume schemes and can be trained via an endtoend differentiable programming framework. The model can achieve nearpeak FLOPs on CPUs and accelerators via convolutional filters.
