The US nuclear program is running low on computing power, with the nation’s top scientists at Sandia National Laboratories turning to unexpected allies to fill the gap: startups.
For decades, Sandia has relied on big-name chip makers like Intel and IBM to provide the brains behind its supercomputers. But as the global chip industry shifts focus to artificial intelligence, these established players are leaving Sandia scrambling for alternatives. The lab’s supercomputers, which handle high-precision simulations for nuclear weapons, are struggling to keep pace.
New Blood in the Supercomputing Scene
Enter the newcomers: startups like Groq and Cerebras Systems. These upstart chip makers are pushing the boundaries of computing power with innovative designs that prioritize efficiency and speed. Sandia is now partnering with these companies to test their cutting-edge chips in its supercomputers.
One such testbed is a nondescript building on Kirtland Air Force Base in New Mexico, where the hum of liquid-cooled supercomputers fills the air. These behemoths crunch complex math problems for the nuclear program, using simulations to model the behavior of materials under extreme conditions. The simulations are critical to ensuring the safety and reliability of the nation’s nuclear arsenal.
AI’s Computing Conundrum
The computing crunch facing Sandia is a symptom of a broader issue: the global chip industry is shifting gears. As AI demand surges, established chip makers are racing to develop specialized chips that can handle the complex computations required by AI models. But this focus on AI is leaving other applications, like scientific simulations, behind.
What this means for Sandia and the nuclear program is a pressing need for alternative computing solutions. By partnering with startups like Groq and Cerebras, the lab is exploring new paths forward. The results of these partnerships will be crucial in determining the future of supercomputing for national security applications.
Sandia’s willingness to partner with newcomers like Groq and Cerebras Systems marks a turning point in the lab’s approach to supercomputing. As the US nuclear program faces a computing crunch, these startups may hold the key to sustaining the nation’s scientific edge.
