Struct MemoryPropertyTable 

pub struct MemoryPropertyTable { /* private fields */ }

A queried memory-property table for one device.

Implementations

impl MemoryPropertyTable

pub fn new(ordinals: Vec<MemoryOrdinalInfo>) -> Self

Build a table from a list of ordinal records.

pub fn len(&self) -> usize

Number of distinct memory ordinals.

pub fn is_empty(&self) -> bool

Returns true when the table has no ordinals.

pub fn ordinals(&self) -> &[MemoryOrdinalInfo]

All ordinals, in driver-reported order.

pub fn select_device_ordinal(&self, bytes: u64) -> LevelZeroResult<u32>

Select the device-memory ordinal best suited for a bytes-sized allocation.

Strategy: among ordinals with enough capacity, prefer the one with the highest reported bandwidth (ties broken by larger capacity, then lower ordinal index). This routes large tensors to HBM on Ponte Vecchio while falling back to whatever fits on memory-constrained parts.

Returns LevelZeroError::OutOfMemory when no ordinal can hold bytes, or LevelZeroError::NoSuitableDevice when the table is empty.

pub fn total_capacity(&self) -> u64

Total capacity across all reported memory ordinals.
