You will need to apply to one of the open access calls that EuroHPC provides. The list of available calls can be found here. 

Our current calls can be found on our website here. 

Researchers from academia, research institutes, public authorities, and industry established or located in an EU Member State, a Participating State or a Horizon 2020-associated third country, are eligible for the Union’s share of access time to EuroHPC supercomputers acquired before 2020. Eligible countries include: Albania, Armenia, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Faroe Islands, Finland, France, Georgia, Germany, Greece, Hungary, Iceland, Ireland, Israel, Italy, Latvia, Lithuania, Luxembourg, Malta, Moldova, Montenegro, Netherlands, North Macedonia, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Tunisia, Türkiye, Ukraine, United Kingdom.

Any European organisation is eligible for access to perform Open Science research (the results of the work are made available for open access). This includes public and private academic and research institutions, public sector organisations, industrial enterprises and SMEs. 

Interested entities will need to apply for access in the context of one of EuroHPC call for system access. The applications are subject to review based on specific conditions set by each call. The types of documents and the information required per access type are available in the related call pages Documents section.

Currently access is free of charge. 

Participation conditions depend on the specific access call that a research group has applied. In general users of EuroHPC systems commit to: 

• acknowledge the use of the resources in their related publications, 
• contribute to dissemination events, 
• produce and submit a report after completion of a resource allocation. 

More information on participation conditions can be found in the call's Documents section.

Access (to the EuroHPC pre-exascale and petascale systems) should be granted to users established in an EU Member State or in a country associated to the Digital Europe Programme or to Horizon Europe, or where applicable, organisations residing, established or located in an EU Member State or in a country associated to Horizon 2020.

In conformity with the EU-UK Withdrawal Agreement, the UK and persons or entities established in the UK continue to be eligible to receive Union funds under actions carried out in direct, indirect or shared management, which implement Union programmes and activities committed under the MFF 2014-2020 until the closure of those Union programmes and activities. This includes Horizon 2020 actions. When restrictions apply, these will be clearly specified in the call for proposals. Since several of the EuroHPC supercomputers are funded by the H2020 programme UK beneficiaries are indeed eligible to apply to access them. 

Competence Centers may request access to specific systems through the Development calls. Access may be granted if this justifiable by the purpose and the scope of the activities foreseen by the Competence Center.

Currently no privileged access is foreseen. 

Since 2010, PRACE has facilitated access to European HPC resources through a competitive peer-reviewed process, where researchers were able to submit proposals for computational projects. The selected projects were granted access to the most advanced supercomputers available in Europe, enabling them to tackle complex scientific challenges and accelerate their research. When the first EuroHPC supercomputers became operational, PRACE agreed to operate, on behalf of the JU,  the peer-review and support process implementing the EuroHPC Access Policy. 

At the end of 2022, the EuroHPC JU, as owner of an increasing number of world-class European supercomputers, took over from PRACE the management of this peer-review and support process. 

During the transition process, the EuroHPC JU has been able to rely on the support of PRACE which has run very similar processes since 2010, benefiting from more than 10 years of experience on the matter and from the trust and collaboration built up over this period with the scientific and industrial communities making use of HPC facilities for their research. 

The EuroHPC JU is very grateful for the support offered by PRACE, helping during the setting up of EuroHPC JU in allowing users to access our supercomputers.
