Control: MareNostrum 5 is owned by the EuroHPC Joint Undertaking and hosted by BSC-CNS, a Spanish public consortium (Spanish government, Generalitat de Catalunya, Universitat Politecnica de Catalunya). No non-EU/EEA corporate parent involved.
Ownership: Same EU-joint-undertaking governance caveat as other EuroHPC entries in this batch; flagged for owner review of the "no-foreign-control" mapping.
Note: Access via competitive national (CPCA) and EuroHPC JU calls, not commercial self-service. New AI partitions targeted for full operation mid-2026 per EuroHPC JU/BSC press materials.
