What is the Lighthouse Codes for HPC Applications Call?
Grant Description
This call supports the development, consolidation, refactoring or extension of globally competitive high-performance computing application codes (“Lighthouse Codes”). It addresses the need for sustainable, production-grade HPC software to enable scientific discovery and drive cross-sector innovation aligned with EU grand challenges. Funded activities include professional software engineering, code optimization and scalability adaptations, comprehensive documentation, validation and reproducibili...
Required Results for Successful Funding
Expected Outcomes
• Production-grade Lighthouse Code integrating cutting-edge HPC and AI capabilities, boosting Europe’s scientific excellence and industrial competitiveness.
• Enhanced scientific and engineering productivity: optimized, consolidated code lowers technical barriers, enabling faster, more accurate exascale simulations and computations.
• Well-documented, high-quality codebases with rigorous validation, reproducibility and comprehensive user/developer documentation.
• Strengthened alignment with EU grand challenges (fusion, advanced batteries, genomics, AI cybersecurity), driving breakthroughs in scientific, industrial and societal domains.
• Sustainable, scalable HPC ecosystem: long-term code stewardship, multi-architecture portability, broad adoption across academia, industry and societal users.
• Establishment of best practices among European HPC contributors and strengthened collaboration with Centres of Excellence and the EuroHPC Academy, fostering community building and training.

Funded areas
Scope Requirements
Proposals must:
• Focus on one existing Lighthouse Code or, in exceptional cases, a reimplemented code based on proven high-impact functionality.
• Demonstrate that the code meets Lighthouse Criteria: professional development structures (HPC software engineers, governance, quality policies); a large/rapidly growing user base (KPIs on users, downloads, resource allocations); systematic documentation (APIs, manuals, developer guides); multi-architecture scalability; code stewardship commitment beyond the grant; clear ownership/licensing framework.
• Align with or build upon HORIZON-EUROHPC-JU-2023-COE-03-01, COE-01-01 and associate as relevant with HORIZON-JU-EUROHPC-2026-COE-LH-01-01/02.
• Present a robust software development plan: defined scope, timeline, milestones, sustainability and measurable KPIs for all selected activities.
• Allocate ≥12 PM for portfolio activities (collaboration tasks) and limit non-technical resources (management, dissemination) to ≤2% of personnel effort.
• Ensure all participants contribute ≥5% of total personnel effort to technical work and deliverables.
• Form a balanced consortium of HPC specialists, domain experts and, where relevant, private-sector partners aligned with business objectives.
• Provide a stewardship letter from a legal entity guaranteeing ongoing maintenance and strategic development.
