New Supercomputing Record Set - Using AMD's Instinct GPUs (tomshardware.com)

(Sunday April 13, 2025 @11:34AM (EditorDavid) from the in-the-chips dept.)


"AMD processors were instrumental in achieving a new world record," [1]reports Tom's Hardware , "during a recent Ansys Fluent computational fluid dynamics simulation run on the Frontier supercomputer at the Oak Ridge National Laboratory."

The article points out that Frontier was the [2]fastest supercomputer in the world until it was beaten by [3]Lawrence Livermore Lab's El Capitan — with both computers powered by AMD GPUs:

> According to a [4]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...

>

> Given those numbers, the Ansys Fluent CFD simulator apparently only used a fraction of the power available on Frontier. That means it has the potential to run even faster if it can utilize all the available accelerators on the supercomputer. It also shows that, despite Nvidia's market dominance in AI GPUs, AMD remains a formidable competitor, with its CPUs and GPUs serving as the brains of some of the fastest supercomputers on Earth.

Clusters have a head node to coordinate the work of the compute nodes. The head node does not process, it just gives them work.

Either the first or CS II.

OpenFoam Prevents $20,000 Seat/Year Fluent Cost (Score:2)

by BrendaEM ( 871664 )

Fluent costs over $20,000, per user, per year, which is a high bar for people who want to cars that are fuel/power efficient. I appreciate the work that everyone has done on OpenFoam. OpenFoam had some early form of GPU solve Hopefully, seeing the test will rekindle the interest in GPU solve, BUT, solve is only part of the problem; the other part of the problem is the mesh, which is only lighter-threaded is also part of the time-consuming CFD process.
