Facts

Source per value

Owner / operator Organization that owns or operates the GPUs. Hosting and facility roles are listed under Partners.: LUMI consortium 1
GPU maker NVIDIA, AMD or Intel, taken from the GPU model.: AMD 2
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 2
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.: 11,912 2
GPU count notes What the count covers (one partition, one site, a design limit), qualifiers and competing figures.: Derived physical packages: 2,978 GPU nodes × 4 MI250X; two dies per package are not double-counted. 2
Location City, region and country where the cluster sits. Empty when the operator does not name the site.: Kajaani, Finland 1
Country Country of the cluster, taken from the location.: Finland 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
Compute nodes nodes Compute nodes in the system or partition.: 2,978 2
HPL performance PFLOP/s Linpack (HPL) result, as published.: 379.7 2
