Facts

Source per value

Owner / operator Organization that owns or operates the GPUs. Hosting and facility roles are listed under Partners.: Oak Ridge Leadership Computing Facility 1
GPU maker NVIDIA, AMD or Intel, taken from the GPU model.: AMD 1
GPU model Accelerator model or family as disclosed. A GH200 is one GPU on a superchip; an MI300A is an APU that contains a GPU.: AMD Instinct MI250X 1
GPUs installed Physical GPUs in the cluster, from the operator or a deterministic sum of disclosed quantities (nodes × GPUs per node). Planned counts, H100-equivalents and unaudited press totals are never counted here.: 39,424 1
GPU count notes What the count covers (one partition, one site, a design limit), qualifiers and competing figures.: Derived physical MI250X packages: 9,856 compute nodes × 4 per node; not 78,848 software-visible dies. 1
Location City, region and country where the cluster sits. Empty when the operator does not name the site.: Oak Ridge, Tennessee, United States 1
Country Country of the cluster, taken from the location.: United States 1
Live power MW Power in service, in megawatts of IT load where the source says so. Company figures are marked in the notes; Epoch AI satellite estimates are labelled as estimates.: Not published
Status operational = running and named as such by the operator or a primary source; partly operational = a phase is live and more is coming; under construction = building underway; announced = disclosed or contracted with no confirmed go-live.: operational 1
Status notes The source’s wording on status, with the date.: Listed in the operator’s current user documentation. 1
Interconnect Cluster network fabric.: HPE Slingshot, 800 Gbps injection per node 1
Compute nodes nodes Compute nodes in the system or partition.: 9,856 1
