Struct PoolStats 

pub struct PoolStats {
    pub allocated_bytes: usize,
    pub peak_bytes: usize,
    pub allocation_count: u64,
    pub free_count: u64,
}

A stream-ordered memory pool (CUDA 11.2+).

Memory pools allow the driver to reuse freed allocations without returning them to the OS, reducing allocation latency and avoiding the implicit synchronisation of cuMemFree.

Status

MemoryPool is a software pool layered on top of cuMemAlloc_v2. For a thin wrapper over the native CUDA stream-ordered memory pool API (cuMemPoolCreate, cuMemPoolDestroy, cuMemAllocFromPoolAsync, cuMemFreeAsync), use NativeMemoryPool.

Statistics for a memory pool’s allocation behaviour.

These statistics track the total bytes allocated, peak usage, allocation count, and free count for a given pool.

Fields

allocated_bytes: usize

Total bytes currently allocated from the pool.

peak_bytes: usize

Peak bytes allocated at any point during the pool’s lifetime.

allocation_count: u64

Total number of allocations performed.

free_count: u64

Total number of frees performed.

Trait Implementations

impl Clone for PoolStats

fn clone(&self) -> PoolStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolStats

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

Formats the value using the given formatter.

impl Default for PoolStats

fn default() -> PoolStats

Returns the “default value” for a type.

impl PartialEq for PoolStats

fn eq(&self, other: &PoolStats) -> 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.

impl Copy for PoolStats
