GRAND EQUIPEMENT NATIONAL DE CALCUL INTENSIF

Their core work

GENCI is France's national high-performance computing (HPC) agency, responsible for coordinating and providing access to supercomputing resources for research and industry across France and Europe. They manage Tier-0 computing infrastructure, participate in European HPC procurement and deployment initiatives, and play a central role in the PRACE ecosystem that gives researchers access to Europe's most powerful supercomputers. Beyond raw computing power, GENCI contributes to HPC governance, training programs, and the strategic roadmapping that shapes Europe's computing infrastructure investments.

What they specialise in

How they've shifted over time

From 2015 to 2019, GENCI focused heavily on traditional HPC infrastructure — operating within the PRACE framework, contributing to European HPC strategy roadmaps, and coordinating the existing ecosystem through EXDCI and EXDCI-2. From 2020 onward, a clear shift appears toward next-generation computing: quantum-HPC hybrids (HPCQS), European processor sovereignty (EPI, EUPEX), and building national competence centres (EUROCC) to bridge HPC skills gaps in industry. The transition signals a move from maintaining current infrastructure to actively building Europe's post-exascale computing future.

GENCI is moving from HPC infrastructure operator toward a builder of Europe's sovereign quantum-classical computing stack — a valuable partner for anyone working at the intersection of quantum computing and large-scale simulation.

How they like to work

GENCI never coordinates H2020 projects but is a consistent, reliable participant and third-party contributor across large European consortia (192 unique partners across 34 countries). Their pattern is institutional: they join as the French national HPC representative in pan-European infrastructure projects, often alongside other national computing centres. This makes them an excellent entry point for anyone needing access to French supercomputing resources or wanting to include a national HPC authority in a consortium bid.

GENCI has collaborated with 192 distinct partners across 34 countries, making them one of the most broadly connected HPC organizations in Europe. Their network spans virtually all EU member states, anchored by deep ties to the PRACE and EuroHPC ecosystems.

What sets them apart

GENCI is not a research lab or a technology company — it is France's national mandate holder for supercomputing, giving it a unique institutional authority that few other HPC partners can offer. Where most HPC participants contribute expertise or code, GENCI brings actual infrastructure access, procurement power (evidenced by the EUR 8.5M PPI4HPC), and a seat at the governance table for European computing strategy. For consortium builders, having GENCI means having France's official supercomputing voice and its Tier-0 machines in your project.

Highlights from their portfolio

• PPI4HPC
  By far their largest funded project (EUR 8.5M) — a public procurement initiative that actually purchased next-generation HPC systems, not just studied them.
• HPCQS
  Marks GENCI's strategic pivot into quantum computing, building a federated quantum-HPC hybrid infrastructure accessible via cloud — their most forward-looking project.
• EUPEX
  Part of the European push for processor sovereignty and exascale capability, connecting GENCI to the European Processor Initiative ecosystem through 2026.
