In May 2022, history was made at Oak Ridge National Laboratory. Frontier, the lab’s newest supercomputer, officially did what no other computer in the world had done before — it crossed the exascale barrier. If you're not familiar with the field of supercomputing, an exascale computer is an incredibly powerful system that is capable of a quintillion calculations per second. Frontier’s arrival marks a new era of computational performance that will help enable scientific breakthroughs never before possible. But this milestone didn't happen overnight. The journey to Frontier has been years in the making, with plenty of challenges and dramatic moments along the way. In this episode, you'll hear a behind-the-scenes account of what it took to launch the world’s first exascale computer.
