1//! # NUMA Topology Detection
2//!
3//! Detects system NUMA topology for thread-per-core architecture.
4//! On multi-socket systems, memory access latency varies by 2-3x depending on
5//! whether memory is local or remote to the CPU.
6//!
7//! ## Components
8//!
9//! - [`NumaTopology`] - Detects system NUMA topology
10//!
11//! ## Platform Support
12//!
13//! | Platform | Support |
14//! |----------|---------|
15//! | Linux | Full NUMA support |
16//! | macOS | Degraded (single node) |
17//! | Windows | Degraded (single node) |
