The US Department of Energy is gearing up to introduce a groundbreaking supercomputer named ATS-5 in 2027. This state-of-the-art system will be pivotal in enhancing national security efforts by bolstering nuclear stockpile management capabilities, signaling the transition to what the DOE terms as the “post-exascale” computing era. ATS-5 is scheduled to be housed at Los Alamos National Laboratory, replacing the current 30-petaflop Crossroads (ATS-3) supercomputer. Equipped with a remarkable 10 petabytes of compute memory within a 20-megawatt power range, ATS-5 is designed to facilitate large-scale 3D simulations crucial for the National Nuclear Security Administration’s (NNSA) objectives. The supercomputer is set to revolutionize defense analysis tasks, drastically reducing completion times and enhancing efficiency. By focusing on faster simulation scaling and improved memory performance to overcome existing challenges, ATS-5 aims to achieve a 10-fold enhancement over its predecessor. Scheduled for delivery in late 2026, this cutting-edge system is poised to set new benchmarks in the realm of supercomputing, with a focus on flexibility and adaptability to evolving technologies. Leading contenders in the development of ATS-5 include HPE and Intel, notable for their expertise in supercomputing projects, promising a bright future for advanced computing capabilities.
