Resource allocation

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 are allocated according to local considerations and policies – so LUMI is seen and handled as an extension to national resources.

The LUMI shares belonging to the EuroHPC JU are 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 is 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 are available to non-European research projects as well. (Note that the Principle Investigator for any projects that apply for time on LUMI needs to be based in the EU or an associated country.)

The resources of LUMI are allocated for projects in terms of three different pools: GPU-hours, CPU-hours, and storage hours. All users of the system have the access to the whole system in accordance with batch job policies, i.e. there are no dedicated hardware for any of the partners.

LUMI also has a channel for urgent computing. This, so called “director’s share”, type of allocation allows 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.

Access to LUMI is handled via Puhuri (more information about Puhuri) which is a cloud service for service providers like HPC centers, supercomputers and data centres for allocating, provisioning and billing compute power, virtual machines and storage. Co-funded by Nordic e-Infrastructure Collaboration (NeIC) and first used by a supercomputer LUMI in Kajaani, Finland, Puhuri is operated by the HPC centre of University of Tartu, Estonia.
