Nothing personal: US government wants to shove 10 million Gigabytes RAM in a 'computer' to do '3D simulation'

The US Department of Energy plans to deploy a massive supercomputer called ATS-5 in 2027 for nuclear stockpile management. With 10 petabytes of compute memory, it will be the largest single-device memory ever. ATS-5 aims to reduce simulation times from months to days and run multiple large-scale "hero" simulations simultaneously. The system will replace the existing Crossroads supercomputer at Los Alamos National Laboratory, targeting a 10x performance improvement for critical workloads within a 20-megawatt power envelope.
