Struct NumaAllocTracker 

pub struct NumaAllocTracker { /* private fields */ }

Per-node accounting of NUMA-bound host allocations.

Tracks how many bytes are currently outstanding on each node so that a scheduler can balance pinned-memory pressure across sockets.

Implementations

impl NumaAllocTracker

pub fn new(topology: &NumaTopology) -> Self

Creates a tracker sized for topology’s node count.

pub fn record(&mut self, buf: &NumaBuffer) -> CudaResult<()>

Records that buf was allocated, adding its bytes to its node’s total.

Errors

• CudaError::InvalidValue if the buffer’s node is out of range for this tracker.

pub fn release(&mut self, buf: &NumaBuffer) -> CudaResult<()>

Records that buf was freed, subtracting its bytes from its node total.

Errors

• CudaError::InvalidValue if the buffer’s node is out of range.

pub fn bytes_on_node(&self, node: usize) -> Option<usize>

Returns the bytes currently outstanding on node, or None if out of range.

pub fn total_bytes(&self) -> usize

Returns the total bytes outstanding across all nodes.

pub fn least_loaded_node(&self) -> Option<usize>

Returns the index of the least-loaded node (fewest outstanding bytes).

Ties are broken by the lowest index. Returns None only if the tracker has zero nodes (which cannot happen via new).

Trait Implementations

impl Clone for NumaAllocTracker

fn clone(&self) -> NumaAllocTracker

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NumaAllocTracker

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for NumaAllocTracker

impl PartialEq for NumaAllocTracker

fn eq(&self, other: &NumaAllocTracker) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
