# Sovereign AI and HPC, Defined

Plain definitions of the terms behind sovereign AI and HPC, from Vantage Compute: secure enclaves, GPU chargeback, fair share, cloud bursting and more.

The Terms

## One sentence each.

### [Secure research computing enclave](https://www.vantagecompute.ai/glossary/secure-research-computing-enclave/)

[A secure research computing enclave is a boundary around compute and data where every user has one identity, access is granted by policy, and every action is audited.](https://www.vantagecompute.ai/glossary/secure-research-computing-enclave/)

### [Sovereign AI](https://www.vantagecompute.ai/glossary/sovereign-ai/)

[Sovereign AI means running AI on infrastructure you control, in your own jurisdiction, so that data never leaves your boundary.](https://www.vantagecompute.ai/glossary/sovereign-ai/)

### [GPU chargeback](https://www.vantagecompute.ai/glossary/gpu-chargeback/)

[GPU chargeback is the practice of attributing GPU usage, and what it cost, to the user, team or project that consumed it.](https://www.vantagecompute.ai/glossary/gpu-chargeback/)

### [Fair-share scheduling](https://www.vantagecompute.ai/glossary/fair-share-scheduling/)

[Fair-share scheduling divides a shared cluster so that each team gets its agreed portion of capacity over time, rather than whoever submits first.](https://www.vantagecompute.ai/glossary/fair-share-scheduling/)

### [Slurm and Kubernetes identity](https://www.vantagecompute.ai/glossary/slurm-and-kubernetes-identity/)

[Slurm and Kubernetes identity means one user identity that works on both schedulers, in place of a separate account on each cluster.](https://www.vantagecompute.ai/glossary/slurm-and-kubernetes-identity/)

### [Cloud bursting](https://www.vantagecompute.ai/glossary/cloud-bursting/)

[Cloud bursting is sending work to cloud capacity when your own clusters are full.](https://www.vantagecompute.ai/glossary/cloud-bursting/)

[Read →](https://www.vantagecompute.ai/glossary/cloud-bursting/)

### [Deny-by-default access](https://www.vantagecompute.ai/glossary/deny-by-default-access/)

[Deny-by-default access means a user can do nothing until a policy grants it.](https://www.vantagecompute.ai/glossary/deny-by-default-access/)
