Third, McIntosh-Smith says exascale could enable “in silico” gas turbine design, in which high-fidelity multi-physics simulations become so accurate and are so trusted that new generations of jet engines could be designed entirely in simulation—and without relying on the slow and expensive process of building a series of physical prototypes. Finally, McIntosh-Smith looks forward to fusion-energy simulation, which could lead to limitless clean energy.
From helping scientists answer some of the biggest questions about physics, chemistry, and human health to facilitating breakthroughs in energy, vehicle design, and manufacturing, exascale computing is an exciting part of what’s to come in the next decade. 2021 and 2022 could be watershed years in ushering in the era of exascale, with supercomputers like Frontier and Aurora just around the corner in the U.S., and international competition not far behind. It’s a compelling time in the history of computing, and society will benefit in myriad ways from achieving exascale.
“Even though we’re facing numerous challenges—for example, the slowing of Moore’s Law and the end of Dennard scaling—the future of computing is even more exciting than the past,” adds McIntosh-Smith. “Today, it’s hard to imagine what computing will be like by 2030 or 2040, as we’re seeing an explosion of different technologies and approaches in order to surmount these challenges. But, however we get there, tremendous new things are going to be possible, literally making the world a better place.”
