We’re trying to mesh health data together and make sense out of it, and that’s a huge challenge. That’s where exascale computing infrastructure, such as Frontier, will be the paradigm shift, because we can bring all of the data together and analyze it in a time efficient way. Imagine having a computational framework that allows us to model an individual’s life trajectory based on their genomic information, and any ancillary information we have about that individual. We could then track that individual throughout their lifetime, and guide them to make informed decisions about their future, taking control of their future before a problem emerges. It’s not the lifespan, it’s the healthspan that matters to all of us.

Director for the National Center for Computational Sciences

This is not a destination as much as it’s a journey, and exascale is the next waypoint on this journey for ever-increasingly more powerful computers. With exascale, we’re going to have smarter AI and we’ll have higher resolution simulations, and it will impact nearly every technology-oriented problem we have, whether it’s climate, fluid dynamics, biology, materials or chemistry. All of this is going to get both a boost from the core compute in exascale, and then an extra boost from applying machine learning, opening up many possible paths for future deployment as well.

The confluence of exascale computing and artificial intelligence will have a transformative impact on all of science. From discovery and design of new drugs to innovative materials and medical treatments, to quantum leaps in our ability to simulate largescale physical phenomena with microscopic high fidelity and accuracy—the impacts of our simulation capabilities will go far beyond anything we have experienced to date.
