Implementations

impl PlatformCapabilities

pub fn detect() -> Self

Detect platform capabilities

This is the main entry point for platform detection as required by SciRS2 policy. All modules should use this instead of direct platform detection.

Detection is performed once per process and cached: probing the host walks every running process and refreshes every CPU (several sysinfo::System scans, ~0.4s a call). Callers such as SimdGateEngine::new construct an engine per circuit evaluation, so an uncached probe here dominated the runtime of anything that simulates in a loop — a 30-step parameter-shift training loop spent over an hour in process enumeration rather than in simulation.

Use crate::platform::get_platform_capabilities to borrow the cached value instead of cloning it.

pub const fn has_simd(&self) -> bool

Check if the platform supports SIMD operations

pub const fn simd_available(&self) -> bool

Check if SIMD is available (compatibility method)

pub const fn gpu_available(&self) -> bool

Check if GPU is available (compatibility method)

pub const fn optimal_simd_width_f64(&self) -> usize

Get the optimal SIMD width for f64 operations

pub fn has_gpu(&self) -> bool

Check if GPU acceleration is available

pub fn primary_gpu(&self) -> Option<&GpuDevice>

Get the primary GPU device

pub const fn is_suitable_for_large_quantum_sim(&self) -> bool

Check if the platform is suitable for large-scale quantum simulation
