Short summary
Scientists use irregular grid models for accurate weather simulation, which help capture details but also make the calculations slow on traditional computers. We redesigned this model for Graphics Processing Units (GPUs) by reorganizing data and calculations. This makes the slowest parts hundreds of times faster and the whole simulation over ten times faster. This allows for higher-resolution simulations.
