Fields

id: usize

name: String

backend: DeviceBackend

memory_mb: u64

compute_units: u32

pci_bus_id: Option<String>

partition_id: Option<String>

Stable partition identifier for sub-device addressing.

For NVIDIA devices this is the GPU UUID (e.g. "GPU-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"), which survives index reordering. For MIG compute instances the MIG UUID (e.g. "MIG-GPU-xxx/0/0") is stored here instead.

Matched by GpuPreference::Partition using the mig:<id> or partition:<id> selector syntax. None for backends that do not expose a stable UUID.

driver_version: Option<String>

Driver version string (when available).

cuda_version: Option<String>

CUDA version string (e.g. “12.0”) for CUDA-capable devices.

compute_capability: Option<String>

CUDA compute capability (e.g. “8.6”) for CUDA devices.

utilization_gpu_pct: Option<u32>

temperature_c: Option<u32>

supports_fp16: bool

supports_int8: bool
