This Bomb-Simulating US Supercomputer Broke a World Record

Brad Settlemyer had a supercomputing solution in search of a problem. Los Alamos National Lab, where Settlemyer works as a research scientist, hosts the Trinity supercomputer—a machine that regularly makes the internet’s (ever-evolving) Top 10 Fastest lists. As large as a Midwestern McMansion, Trinity’s main job is to ensure that the cache of US nuclear weapons works when it’s supposed to, and doesn’t when it’s not.

The supercomputer doesn’t dedicate all its digital resources to stockpile stewardship, though. During its nuclear downtime, it also does fundamental research.

Settlemyer wanted to expand the machine's scientific envelope. So he set out in search of a problem that even Trinity couldn’t currently solve. What he found was a physicist who wanted to follow only the most energetic particles through a trillion-particle simulation—a problem whose technological solutions have surprising implications for the bomb babysitters at Los Alamos.
