EuroHPC Joint Undertaking (EuroHPC JU) has announced access calls for 2025. Researchers from academia, research institutes, public authorities, and industry can apply for computational resources of supercompters co-funded by EuroHPC JU.
EuroHPC JU offers from 35% of the total capacity of petascale systems up to 50% of pre-exascale systems in access calls. This also applies to the Karolina supercomputer at IT4Innovations, where 35% of the capacity is reserved for projects submitted through EuroHPC JU calls.
User support
In addition to computational resources, users can also benefit from expert support from the High Level Support Team (HLST), which helps with code optimisation, data management and efficient use of supercomputing resources. This support is provided by the EPICURE project. Find out more in this presentation by João Barbosa from IT4Innovations, which was given at the Users' Conference of IT4Innovations in November 2024.
EuroHPC supercomputers
Petascale systems:
- Karolina (Czechia) – https://docs.it4i.cz/karolina/hardware-overview/
- MeluXina (Luxembourg) – https://docs.lxp.lu/
- Discoverer (Bulgaria) – https://docs.discoverer.bg/resource_overview.html
- Vega (Slovenia) – https://doc.vega.izum.si/general-spec/
- Deucalion (Portugal) – https://docs.deucalion.macc.fccn.pt/
Pre-exascale systems:
- LUMI (Finland) – https://docs.lumi-supercomputer.eu/
- Leonardo (Italy) – https://leonardo-supercomputer.cineca.eu/hpc-system/
- MareNostrum 5 (Spain) – https://www.bsc.es/marenostrum/marenostrum-5
EuroHPC access modes
- Benchmark Access – testing or benchmarking software.
- Development Access – access to a small number of node hours for application development, testing and optimisation. Used as preparation before requesting more extensive access.
- AI and Data-Intensive Applications Access – for industry organisations, small to medium enterprises (SMEs), startups, as well as public sector entities, requiring access to supercomputing resources to perform artificial intelligence and data-intensive activities. Cut-off dates for 2025 are being updated and will be published soon.
- Regular Access – access to large-scale computational resources for research domains, industry open R&D and the public sector. In 2025, there will be two calls.
- Extreme Scale Access – access for innovative, high-impact projects that require large computational resources. Two calls will be launched in 2025. Successful applicants will receive access to pre-exascale supercomputers or Jupiter.
Please note! Unlike IT4Innovations Open Access Grant Competition calls, EuroHPC JU always closes its calls at 10 AM on the given date.
For 2025, EuroHPC JU has set the following application deadlines:
| Access mode | computational resources | Deadline for submission of the application | duration of allocation and main deadlines |
|---|---|---|---|
| Benchmark Access | petascale and pre-exascale systems (including Karolina) | by the 1st of each month | max. 3 months; access within 3 weeks after the date of submission |
| Development Access | petascale and pre-exascale systems (including Karolina) | by the 1st of each month | 12 months; access within 3 weeks after the date of submission |
| AI and Data-Intensive Applications Access | pre-exascale systems | cut-off dates will be published soon | 12 months; decision within one month after the date of cut-off |
| Regular Access | petascale and pre-exascale systems (including Karolina) | 28 March; 5 September | 12 months; decision within four months after the date of cut-off |
| Extreme Scale Access | pre-exascale systems + JUPITER | 18 April; 17 October | 12 months; decision within six months after the date of cut-off |
*Cut-off dates for AI and Data-Intensive Applications Access are being updated. The new timeline will be published soon.
