Title: New Supercomputing Record Set - Using AMD's Instinct GPUs

Link: https://tech.slashdot.org/story/25/04/13/0130...

"AMD processors were instrumental in achieving a new world record," 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 fastest
supercomputer in the world until it was beaten by Lawrence Livermore Lab's El
Capitan - with both computers powered by AMD GPUs: 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...
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.
