AMD processors were instrumental in achieving a new world record during a recent Ansys Fluent computational fluid dynamics (CFD) simulation run on the Frontier supercomputer at the Oak Ridge National Laboratory (ORNL). According to a press release by Ansys, it ran a 2.2-billion-cell axial turbine simulation for Baker Hughes, an energy technology company, testing its next-generation gas turbines aimed at increasing efficiency. The simulation previously took 38.5 hours to complete on 3,700 CPU cores. By using 1,024 AMD Instinct MI250X accelerators paired with AMD EPYC CPUs in Frontier, the simulation time was slashed to 1.5 hours. This is more than 25 times faster, allowing the company to see the impact of the changes it makes on designs much more quickly.
A new supercomputing record has been set!Ansys, @bakerhughesco, and @ORNL have run the largest-ever commercial #CFD simulation using 2.2 billion cells and 1,024 @AMD Instinct GPUs on the world’s first exascale supercomputer. The result? A 96% reduction in simulation run…April 4, 2025
