NCAR has won an HPCwire Editor's Choice award for Best Use of HPC in the Physical Sciences for developing the GPU-based FastEddy model, which can run weather forecasts at a resolution of just five meters (16 feet).

FastEddy, which was trained on CISL’s Casper cluster, is a new resident-GPU microscale large-eddy simulation (LES) model coupled with the Weather Research and Forecasting (WRF) model. The model is capable of providing real-time weather hazard avoidance at the microscale level and allows scientists to predict how weather and buildings in an urban environment affect drones and other small aerial vehicles.

Additional development efforts aim to scale execution across up to 12,288 Nvidia V100 GPUs of the Oak Ridge Leadership Computing Facility’s Summit architecture.
