About the service
Documentation updated: 15 September 2026.
This page describes how the KBFI HPC service is organized, who may use it and the conditions under which resources are provided. For a general introduction, approximate scale and research context, see the Home page.
Organization
| Item | Description |
|---|---|
| Service owner | National Institute of Chemical Physics and Biophysics (KBFI; NICPB in English) |
| Operating group | KBFI High Energy Physics group |
| National infrastructure | Estonian Scientific Computing Infrastructure (ETAIS) |
| Location | Akadeemia tee 23, Tallinn, Estonia |
The infrastructure was developed through ETAIS. Its international role and collaboration identifiers are documented on the International collaboration page.
Access and allocation
| User group | Access model |
|---|---|
| CMS collaboration | Collaboration-managed production allocation |
| KBFI High Energy Physics | Local accounts and scheduled resources |
| Other KBFI groups | Available capacity allocated using local fair share |
| External researchers | Access through ETAIS and through scientific-cooperation agreements |
CMS production is the service's primary commitment and provides a stable base load. Local and external research users have access to the full cluster capacity through fairshare. External projects should discuss expected CPU, GPU and storage needs with the cluster team before applying.
Service conditions
Unless separately agreed, access to resources and technical support is provided on an as-is, best-effort basis.
- Local workloads are scheduled using fair share rather than fixed individual allocations.
- Issues are fixed and new features are deployed on a best-effort basis.
- Weekends, public holidays, vacation periods, extreme electricity prices or extreme weather may result in reduced availability.
- Jobs are normally limited to 48 hours.
These conditions should be considered when planning time-sensitive or long-running work.
Access and support
- To request an account, follow the access instructions.
- External users should also review the published prices.
- For account and infrastructure questions, see Contact details.
Technical users can find current, dated specifications under Compute nodes and Storage.
