Facts
Source per value- Owner / operator Organization that owns or operates the GPUs. Hosting and facility roles are listed under Partners.
- Lawrence Livermore National Laboratory 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 MI300A APU 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.
- 46,080 1
- GPU count notes What the count covers (one partition, one site, a design limit), qualifiers and competing figures.
- Published total includes batch, debug and login nodes; each MI300A APU contains a GPU. 1
- Location City, region and country where the cluster sits. Empty when the operator does not name the site.
- Livermore, California, 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.
- Limited availability in the operator’s current documentation. 1
- Interconnect Cluster network fabric.
