The first call for proposals for the EuroHPC Joint Undertaking (EuroHPC JU) regular access mode is open. Researchers from academia, research institutes, public authorities, and industry established or located in an EU Member State or in a country associated with Horizon 2020 can now apply and access the EuroHPC pre-exascale and petascale supercomputers. 

The computing resources of the EuroHPC JU are now available to support large-scale European projects with important needs in terms of compute time, data storage, and support resources. The call is open to all fields of science, industry, and the public sector. The projects should be designed to enable progress and innovation in their respective domains. The computer systems that will undertake the operations for the projects chosen for this regular access call are: VEGAin Slovenia, MeluXina in Luxembourg,Discoverer in Bulgaria, Karolina in the Czech Republic, and LUMI in Finland.  

The call is continuously open with pre-defined cut-off dates (three per year) that will trigger the evaluation of the proposals submitted up to this date. The first cut-off date is Friday 3 December 2021, 10:00 AM CET. The next indicative cut-off dates for proposals are: 

  • 4 March 2022 – 10:00 AM CET 
  • 1 July 2022 – 10:00 AM CET 
  • 4 November  2022 – 10:00 AM CET *

The EuroHPC JU’s access resource committee, composed of leading European experts, will rank the proposals received and produce a recommendation to award EuroHPC JU resources based on scientific and technical excellence.   

Computation time will be allocated to eligible European users, matching their application requirements, according to the principles stated in the EuroHPC JU Council Regulation and the JU’s Access Policy. The allocations will be granted for one year with the option for projects to apply for a continuation. This continuation shall be duly justified, limited to a maximum of one additional year, and will depend on an assessment of their ongoing awarded project.

The Regular Access call is organised by the EuroHPC JU with the support of PRACE (Partnership for Advanced Computing in Europe).  All proposals must be submitted via the PRACE Peer-Review Tool. Further details about the standard application procedure can be found in the following links:


The EuroHPC JU enables the coordination of efforts and the sharing of EuroHPC resources with the objective of deploying a world-class HPC infrastructure and a competitive innovation ecosystem in supercomputing technologies, applications, and skills in Europe.  

 The EuroHPC JU has procured seven supercomputers, located across Europe. Five of them are now operational: Vega in Slovenia, MeluXina in Luxembourg, Discoverer in Bulgaria, Karolina in the Czech Republic and LUMI in Finland.  The JU is managing the EU access time of these supercomputers, from 35% up to 50% of their total capacity.
