Struct HardwareProfile 

pub struct HardwareProfile {
    pub backend: HardwareBackend,
    pub has_cuda: bool,
    pub has_rocm: bool,
    pub cpu_logical_cores: usize,
    pub has_avx2: bool,
    pub has_avx512: bool,
}

Detected hardware capabilities.

Fields

backend: HardwareBackend

Active GPU backend (highest priority GPU, or CpuSimd when none found).

has_cuda: bool

CUDA-capable GPU found at runtime (NVIDIA only; requires gpu feature at compile time).

has_rocm: bool

AMD ROCm/HIP GPU found at runtime.

cpu_logical_cores: usize

Logical CPU cores available to rayon’s global thread pool.

has_avx2: bool

x86_64: AVX2 support detected via CPUID.

has_avx512: bool

x86_64: AVX-512F support detected via CPUID.

Implementations

impl HardwareProfile

pub fn detect() -> Self

Probe the current machine’s capabilities.

pub fn recommend_ivf_pq(&self, n_vectors: usize) -> bool

True when IVF-PQ training is justified for a dataset of n_vectors vectors.

Returns false when:

• n_vectors < MIN_VECTORS_FOR_IVF_PQ (k-means clusters would be meaningless)
• Neither GPU (CUDA or ROCm) nor a sufficiently parallel CPU is available
