CLUSTERATLASUniversity of Bristol
Isambard-AI phase 2 is operated by University of Bristol in United Kingdom. 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.
Figures are for Phase 2 alone. Bristol news articles quote 1,362 nodes and 5,448 superchips, which combine Phase 1 (42 nodes) with Phase 2 (1,320); those combined figures are not used here. 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.
