The Aurora supercomputer, one of the most powerful machines ever built, sits in a federal lab in the Chicago suburbs, and almost nobody around here talks about it. While the city argues about stadiums and startups, Argonne National Laboratory in Lemont has been quietly running a computer that does more math in a second than you could do in several lifetimes.
What Aurora actually is
According to Argonne, Aurora is one of the world’s first exascale supercomputers, meaning it can perform more than a quintillion calculations per second. It was deployed in November 2023 and built in partnership with Intel and Hewlett Packard Enterprise, at an estimated cost of around $500 million. According to the TOP500 rankings, it was briefly the second-fastest supercomputer on the planet after coming online. It lives at the Argonne Leadership Computing Facility, a Department of Energy Office of Science user facility, and it draws nearly 39 megawatts of power, which is to say it eats electricity like a small town.
It is an AI machine, not just a science one
This is the part people miss. Aurora was designed for artificial intelligence and simulation at a scale that was simply impossible before. According to Argonne, it powers work on fusion energy, materials science, energy storage, and cancer research, the kind of problems where you need to model reality at brutal resolution. In an era where every AI conversation is about who has the most compute, a machine like this in your backyard is not a trivia fact. It is infrastructure.
Why this belongs in Chicago’s tech story
I keep coming back to the same theme. Chicago’s tech strength is rarely loud, and Aurora is the perfect example. It connects directly to the rest of the region’s bets: Argonne does the battery research that underpins the Illinois EV corridor, its compute feeds the research base behind the state’s quantum and microelectronics ambitions, and it anchors the argument that Chicago is a serious AI hub rather than a hopeful one. National labs are the unglamorous superpower most cities would kill for.
If Chicago marketed Aurora the way the coasts market a new model launch, people would talk about it for weeks. Instead it just sits in Lemont doing world-class science with no press tour. That is very on brand for this region, and a little frustrating, because the compute that everyone is fighting over right now has been humming away in the suburbs the whole time.
