CLUSTERATLASEuroHPC/NAISS (National Academic Infrastructure for Supercomputing in Sweden)
Arrhenius GPU is operated by EuroHPC/NAISS (National Academic Infrastructure for Supercomputing in Sweden) in Sweden. This profile covers Ranked system / partition. Specifications are listed below; anything the operator has not published is itemised in the documented-fields list.
Items marked ▧ come from the documented NVIDIA GH200 Grace Hopper Superchip platform specification.
NAISS lists the interconnect as "4x Slingshot 200 GB"; the unit as written is ambiguous, so a per-adapter rate is not recorded. NAISS also gives 29 PB for the parallel file system on its resource page against 25 PB disk plus 2 PB flash in the technical description, and does not reconcile the two. Node specifications follow the documented NVIDIA GH200 Grace Hopper Superchip platform (Superchip module — nodes per system and per-node superchip counts are operator-specific); operator-specific deviations are not published.
Every field this catalog checks. Fields listed above have a value; the remainder are shown here. A field marked absent is not publicly available in the sources we could verify, which does not mean the hardware is missing. Fields that cannot apply, such as benchmark results for an unranked system, are excluded from the total.
