Ansys, Baker Hughes, and Oak Ridge National Laboratory (ORNL) have achieved a new world record in supercomputing. The collaboration used the Frontier exascale supercomputer, powered by AMD EPYC processors and AMD Instinct MI250X GPUs, to perform computational fluid dynamics (CFD) simulation at an unprecedented scale.
An achievement in CFD simulation
This achievement is based on running Ansys’ Fluent simulation software , which, when combined with 1,024 AMD Instinct GPUs, reduced simulation time by an impressive 96% , from 38.5 hours using 3,700 CPU cores to just 1.5 hours. This acceleration optimizes costs and reduces development timelines, enabling faster and more efficient innovation in the energy sector .
The simulation of an axial turbine stator with 2.2 billion cells is a clear example of how exascale supercomputers, such as Frontier, can offer detailed insights into complex physical phenomena , helping companies like Baker Hughes optimize their next-generation gas turbines and improve overall energy efficiency.
Furthermore, advances in the use of GPUs in CFD simulations are opening up new possibilities for small and medium-sized companies, which can now perform high-fidelity simulations without access to exascale infrastructure. With increased computational efficiency, these companies can optimize their products and processes at a fraction of the cost.
