Half of the LUMI resources belong to the EuroHPC Joint Undertaking, and the other half of the resources belong to the participating countries i.e. the LUMI consortium countries.
Each consortium country has a share of the resources based on the country’s contribution to the LUMI funding. The shares for each of the countries will be allocated according to local considerations and policies – so LUMI will be seen and handled as an extension to national resources.
The LUMI shares belonging to the EuroHPC JU will be allocated by a peer-review process (comparable to that used for PRACE Tier-0 access). In addition, up to 20% of the EuroHPC resources will be available to industry and SMEs.
A researcher affiliated with one of the LUMI consortium countries or a company which has its headquarters in the LUMI consortium countries will be able to apply for LUMI resources via the LUMI consortium country’s national share and, in addition, via EuroHPC’s technical and scientific peer-review process.
By partnering with European research groups and/or companies, the EuroHPC resources will be available to non-European research projects as well. (Note that the Principle Investigator for any projects that apply for time on LUMI will need to be based in the EU or an associated country.)
The peer-review and application processes are still under negotiation and further details will be announced later closer to the opening of LUMI.
The resources of LUMI will be allocated for projects in terms of three different pools: GPU-hours, CPU-hours, and storage hours. All users of the system will have the access to the whole system in accordance with batch job policies, i.e. there will be no dedicated hardware for any of the partners.
LUMI will also have a channel for urgent computing. This, so called “director’s share”, type of allocation will allow to grant some of LUMI’s resources on an ad hoc basis for time- and mission-critical simulations. This kind of simulations might be, for example, related to national or EU security, or some massive disturbance affecting the partner countries, for example a large epidemia or pandemic disease.
