Supercomputers keep getting faster. Just a few years ago it took teraflops — or trillions of floating point operations per second — to make the list of the world’s fastest computers. Now it takes exaflops, quintillions of operations per second. And now the Oak Ridge National Laboratory has switched on a machine that makes 1.1 exaflops of performance. It’s called Frontier. Federal Drive host Tom Temin talked about Frontier with Oak Ridge distinguished scientist and Frontier project officer, Scott Atchley.
