AMD GPUs Shatter CFD Simulation Record on Frontier Supercomputer
2025-04-13

AMD processors powered a new world record in computational fluid dynamics (CFD) simulation using Ansys Fluent on the Frontier supercomputer. A 2.2-billion-cell simulation, previously taking 38.5 hours on 3,700 CPU cores, completed in just 1.5 hours using 1,024 AMD Instinct MI250X accelerators and AMD EPYC CPUs. This 25x speedup highlights AMD's prowess in high-performance computing. However, challenges remain in software support, hindering AMD's ability to fully compete with Nvidia in the AI GPU market, as illustrated by instances like Tiny Corp's preference for Nvidia GPUs due to driver stability.
