Aggregate Rmax is the sum of the systems this company supplies any part of. It is not revenue and not attributable share: an integrator and a memory vendor in the same machine both count its full FLOPS here. Attribution weighted by role is Phase 4.

Related news
- Bull Expands Supercomputer Manufacturing with €80M Angers Redevelopment · HPCwireAngers is the one European plant assembling Eviden's BullSequana systems, including the Alice Recoque and LUMI-AI builds already tracked here, so this €80M capacity doubling (due 2028) is a concrete signal on whether those deliveries stay on schedule. It also surfaces a new Foxconn partnership to build NVIDIA Vera Rubin NVL72 AI servers in Europe, relevant to the EU domestic-substitution question raised elsewhere in this dataset.
- French state completes its acquisition of Bull from Atos · Atos GroupThe state becomes sole owner of Bull's HPC, quantum and AI divisions for up to 404 million euros, nine months after the July 2025 purchase agreement, formalizing Bull as a sovereign supplier rather than a subsidiary of a financially troubled parent. Bull's BullSequana platform underpins JUPITER, so this is a change of ownership sitting directly upstream of an existing exascale system in this dataset, not just a balance sheet event.
