## OpenStack Cyborg (GPU lifecycle management)
|
||||
|
||||
Cyborg je OpenStack service pro správu akcelerátorů (GPU, FPGA, DPU, NPU).
|
||||
|
||||
### Klíčové schopnosti
|
||||
|
||||
- **Discovery** — automatická detekce GPU na compute node (NVIDIA, AMD, Intel)
|
||||
- **Inventory** — tracking dostupných akcelerátorů v clusteru
|
||||
- **Lifecycle** — attach/detach GPU k VM, firmware update, reset
|
||||
- **Scheduling** — Placement API pro GPU-aware scheduling (Nova)
|
||||
- **Cyborg API** — REST API pro správu akcelerátorů
|
||||
|
||||
### Integrace
|
||||
|
||||
| Komponenta | Role |
|
||||
|------------|------|
|
||||
| **Nova** | VM scheduling s GPU požadavky (extra_specs: `accel:device_profile`) |
|
||||
| **Placement** | Resource provider pro GPU (inventory, traits) |
|
||||
| **Neutron** | SR-IOV VF passthrough pro GPU networking |
|
||||
| **Ironic** | Bare metal + GPU provisioning |
