The most powerful supercomputers on the planet are used to perform all manner of complex operations. Increasingly, they are used to enable artificial intelligence for research that could one day impact billions of people. The world’s fastest and most powerful high-performance computing (HPC) supercomputers are front and center at the International Supercomputing Conference (ISC).

HPC plus AI is really the transformational tool of scientific computing,” Dion Harris, Nvidia marketing manager for accelerated computing, said in a media briefing ahead of ISC. “We talk about exascale AI because we do believe that this is going to be one of the key pivotal tools to drive scientific innovation and any data center that’s building a supercomputer needs to understand how their system will perform from an AI standpoint.

Los Alamos National Laboratory and Hewlett Packard Enterprise (HPE) are building Venado, which is the first U.S. based supercomputer to use the Grace chip architecture. The Venado supercomputer uses a combination of Grace and Grace Hopper superchips, in a system that is expected to deliver 10 exaflops of AI performance. The Venado system will be used for material science, renewable energy, as well as energy distribution research.

As people around the world try to find solutions to the challenges of global warming, one of the primary strategies is to identify renewable energy sources. One such source could be nuclear reactors. Today’s nuclear reactors are fission-based and generate radioactive waste. The promise of fusion is that it can deliver large amounts of energy, without the same waste as fission. The U.K. Atomic Energy Authority (AEA) is using the Nvidia Omniverse simulation platform to accelerate the design and development of a full-scale fusion reactor. “With the Nvidia Omniverse, researchers could potentially build a fully functioning digital twin of a reactor, helping ensure the most efficient designs are selected for construction,” Harris said.

The goal for Omniverse and the digital twin is to have an AI-generated replica of the fusion reactor system. The U.K. AEA is also planning to simulate the physics of the Fusion plasma containment itself.The holy grail of fusion energy is being able to not just create a fusion reaction, but have it be sustainable,” Harris added. “We really think this will be a path towards sustainable energy.”
