Struct NumaTopology 

pub struct NumaTopology {
    pub nodes: Vec<NumaNode>,
    pub gpu_node_map: HashMap<u32, u32>,
}

NUMA topology information for a system.

Fields

nodes: Vec<NumaNode>

gpu_node_map: HashMap<u32, u32>

GPU-to-NUMA-node mapping (gpu_id -> node_id).

Implementations

impl NumaTopology

pub fn detect() -> Self

Detect NUMA topology from the system. On non-Linux or single-node systems, returns a single flat node.

fn detect_linux() -> Result<Self>

pub fn gpu_numa_node(&self, gpu_id: u32) -> Option<u32>

Get the NUMA node that a GPU is connected to.

pub fn cpus_for_gpu(&self, gpu_id: u32) -> Vec<u32>

Get CPUs on the same NUMA node as a given GPU.

pub fn select_cpu( &self, gpu_id: Option<u32>, cpu_loads: &HashMap<u32, f32>, ) -> u32

Select the best CPU for a task given its GPU affinity. Returns the CPU ID from the preferred NUMA node with the lowest load.

pub fn total_cpus(&self) -> usize
