AI-powered supercomputer to start testing America's nukes

Scientists have unveiled the world's fastest computer in California that will be used to secure America's nuclear weapons stockpile. The 600 million exascale supercomputer, called'El Capitan,' is only the third of its kind in the world. That's equivalent to the processing power of about one million high-end smartphones working simultaneously, researchers said. El Capitan launched at the Livermore National Laboratory (LNNL) in November 2024 and was officially announced to the public on January 9. It will primarily focus on national security, including nuclear data and weapon testing, high-energy-density physics, materials discovery and other sensitive or classified tasks.
