Nvidia, Oracle to build AI supercomputer for U.S. Department of Energy

Nvidia (NVDA) announced a landmark collaboration with Oracle (ORCL) to build the U.S. Department of Energy’s largest AI supercomputer to dramatically accelerate scientific discovery. The Solstice system will feature a record-breaking 100,000 Nvidia Blackwell GPUs and support the DOE’s mission of developing AI capabilities to drive technological leadership across U.S. security, science and energy applications. Another system, Equinox, will include 10,000 Nvidia Blackwell GPUs and is expected to be available in the first half of 2026. Both systems will be interconnected by Nvidia networking and deliver a combined 2,200 exaflops of AI performance. The Solstice and Equinox supercomputers will be located at Argonne National Laboratory. They will enable scientists and researchers to develop and train new frontier models and AI reasoning models for open science using the Nvidia Megatron-Core library and scale them using the Nvidia TensorRTinference software stack. These models will form the backbone of agentic AI workflows for scientific discovery. Both AI supercomputers will support Nvidia, Argonne and the DOE’s research collaborations to develop agentic scientists, boosting R&D productivity and accelerating discovery enabled by public research dollars within a decade. Solstice will be built with the DOE’s new public-private partnership model, including industry investments and use cases.
