## LUMI

- `compute/lumi` | fails-identity | evidence documented | binding write-gated | category national HPC allocation
- needs card unknown, phone unknown, ID no, institution yes | verified 2026-10-22 (live) | stale on 2026-11-22
- url https://docs.lumi-supercomputer.eu/firststeps/accessLUMI/
- free tier: Access to LUMI requires membership of a project that has already been granted resources. | unit: hours | metered on: wall-clock | read on: 2026-10-22 | source: [1] | note: national consortium allocation
- per-object cap: not applicable | source: [1]
- retention: not applicable | source: [1]
- egress: not stated | metered: no | source: [1]
- identity: institution | detail: The consortium covers Belgium, Czechia, Denmark, Estonia, Finland, Iceland, Netherlands, Norway, Poland, Sweden, Switzerland plus EuroHPC JU; the Finnish route needs affiliation with a Finnish higher-education or research institute, or an organisation established or located in Finland. No card, hold, phone number or ID document is stated: unknown.
- interface: unknown
- limits:
  - write-gated (binding): There is no LUMI-wide application: a person must be invited into a project by a national Resource Allocator, so the door is a national affiliation in one of 13 countries, and the alternative CSC route requires affiliation with a Finnish institution. [1]
- limits note: There is no LUMI-wide application: a person must be invited into a project by a national Resource Allocator, so the door is a national affiliation in one of 13 countries, and the alternative CSC route requires affiliation with a Finnish institution.
- binding note: the same as limits note
- interface detail: inferred from the tooling the provider documents; not probed
- tooling: not stated
- composes with: The only LUMI route that does not need a consortium affiliation is the EuroHPC call stack recorded separately, and that stack is gated on an EU-affiliated organisation rather than on a LUMI country.
- reliability: no reliability event recorded
- notes: There are 12 national allocators plus the EuroHPC JU, and they are the only entries. The Finnish national route states a useful floor of 1 million core hours for a developer project, which is the clearest published size found for a LUMI national allocation. GPU-hour figures for LUMI-G are set per national allocator and are not published centrally, so the field is null rather than borrowed from the EuroHPC tables.
- extras:
  - facets.class: national-hpc
  - facets.free_tier_kind: national consortium allocation
  - facets.shape.gpu_class: AMD MI250X (LUMI-G)
- evidence:
  - [1] 2026-10-22: 'To access LUMI, you need to be a member of a project that has been granted resources on LUMI. The LUMI consortium countries have different policies for accessing LUMI'; 'a Resource Allocator (RA) must create a project and invite the Principal Investigator', quoted
  - [1] 2026-10-22: consortium list covers Belgium, Czechia, Denmark, Estonia, Finland, Iceland, Netherlands, Norway, Poland, Sweden, Switzerland plus EuroHPC JU
  - [2] 2026-10-22: 'You can apply for the national LUMI resources either as an academic user affiliated with a Finnish higher-education or research institute or as an industry user from an organization established or located in Finland'; 'Developer project access starts from 1 million core hours', quoted

## LUMI-O (CSC / EuroHPC LUMI) — 150 TB allocated per LUMI project by default

- `storage/lumi-o-150-tb-allocated-per-lumi-project-by-default` | fails-identity | evidence documented | binding none | category academic
- identity a placeholder: card and phone unknown | verified 2026-10-22, checked 2026-10-21 (inherited) | stale on 2026-11-21
- url https://docs.lumi-supercomputer.eu/storage/lumio/
- free tier: 'LUMI-O offers a total of 30 PB storage space ... By default 150 TB of storage space is allocated per LUMI project, but projects can request for more LUMI-O storage space by contacting the LUMI helpdesk.' This is the single largest default per-project object-storage quota found in the entire survey. | unit: TB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: not stated | source: [1] | note: not stated
- egress: Unmetered; public buckets and presigned URLs are served over HTTPS. 'It is possible to share public data across the internet (for the duration of your project)' and 'to set a temporary access link to otherwise private data'. | metered: no
- identity: institution | detail: inferred from the category 'academic'; the source record states no identity cost, so this is a class assumption, not evidence
- interface: s3, rclone, cli
- limits note: per-object-cap: 500,000 objects per bucket, same as Allas. No per-object byte cap documented. Retention is the project lifetime, explicitly: 'Data lifetime in LUMI-O is the same as your project lifetime.' request-rate: not published. Note: 'In LUMI-O one project is treated as one account: all project members have the same access/user rights' — so quota is per project, never per person.
- binding note: 150 TB per LUMI project needs a LUMI/EuroHPC project; the endpoint answers anonymously and issues nothing. Identity binds before any limit does.
- interface detail: s3
- tooling: rclone, s3cmd, aws cli, LUMI web interface. Credentials are LUMI-O access tokens generated at auth.lumidata.eu, scoped to a project.
- composes with: 150 TB × N LUMI projects. A LUMI project is the unit; Finnish researchers create LUMI projects through MyCSC (the 'LUMI' project category) and LUMI is also reachable through EuroHPC Benchmark/Regular access and through national shares (e.g. SURF's Small Compute applications include 'up to 100,000 TB-hours project space storage' on LUMI). Every LUMI project carries LUMI-O by default: 'All LUMI projects have LUMI-O available by default.'
- reliability: Data dies with the project; no backup is implied and objects cannot be modified in place.
- notes: 'LUMI-O offers a total of 30 PB storage space ... By default 150 TB of storage space is allocated per LUMI project, but projects can request for more LUMI-O storage space by contacting the LUMI helpdesk.' This is the single largest default per-project object-storage quota found in the entire survey. VERDICT: fails-identity. Quota and gate in one sentence: 150 TB per LUMI project by default out of 30 PB, reachable only through a LUMI or EuroHPC project allocation, so the quota is real and unreachable for a user.
- evidence note: The page states the number in the record; the claim is documented, not measured. The verdict is fails-identity on the registration gate; the quota is documented and the gate is documented.
