Overview
- Two DOE systems—Solstice with about 100,000 Nvidia Blackwell GPUs and Equinox with about 10,000—will be installed at Argonne National Laboratory.
- Together the machines are slated to deliver roughly 2,200 exaflops of AI performance using Nvidia’s high-speed networking.
- Equinox is scheduled to go live in the first half of 2026, with construction at Argonne beginning immediately and Solstice targeted for delivery in 2026.
- The platforms will support training of frontier models and development of agentic AI scientists using Nvidia’s Megatron-Core and TensorRT software.
- Officials describe a public–private partnership to bolster U.S. leadership, with Oracle providing sovereign capabilities via OCI and Argonne preparing broad researcher access and links to facilities such as the Advanced Photon Source.
