Source per value

Owner / operator Organization that owns or operates the GPUs. Hosting and facility roles are listed under Partners.: CSCS 1
GPU maker NVIDIA, AMD or Intel, taken from the GPU model.: NVIDIA 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.: NVIDIA GH200 (H100 GPU) 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.: 10,752 1
GPU count notes What the count covers (one partition, one site, a design limit), qualifiers and competing figures.: Grace Hopper partition only; other Alps GPU partitions excluded. 1
Location City, region and country where the cluster sits. Empty when the operator does not name the site.: Lugano and Lausanne, Switzerland 1
Country Country of the cluster, taken from the location.: Switzerland 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
Operational since Month or year the source gives for the cluster going live (first phase for partly operational clusters). Empty when no date is published.: 2024-09 1
Status notes The source’s wording on status, with the date.: Inaugurated September 2024 1
