Implementations

impl cudaMemPoolAttr

pub const cudaMemPoolReuseFollowEventDependencies: cudaMemPoolAttr

(value type = int) Allow cuMemAllocAsync to use memory asynchronously freed in another streams as long as a stream ordering dependency of the allocating stream on the free action exists. Cuda events and null stream interactions can create the required stream ordered dependencies. (default enabled)

impl cudaMemPoolAttr

pub const cudaMemPoolReuseAllowOpportunistic: cudaMemPoolAttr

(value type = int) Allow reuse of already completed frees when there is no dependency between the free and allocation. (default enabled)

impl cudaMemPoolAttr

pub const cudaMemPoolReuseAllowInternalDependencies: cudaMemPoolAttr

(value type = int) Allow cuMemAllocAsync to insert new stream dependencies in order to establish the stream ordering required to reuse a piece of memory released by cuFreeAsync (default enabled).

impl cudaMemPoolAttr

pub const cudaMemPoolAttrReleaseThreshold: cudaMemPoolAttr

(value type = cuuint64_t) Amount of reserved memory in bytes to hold onto before trying to release memory back to the OS. When more than the release threshold bytes of memory are held by the memory pool, the allocator will try to release memory back to the OS on the next call to stream, event or context synchronize. (default 0)

impl cudaMemPoolAttr

pub const cudaMemPoolAttrReservedMemCurrent: cudaMemPoolAttr

(value type = cuuint64_t) Amount of backing memory currently allocated for the mempool.

impl cudaMemPoolAttr

pub const cudaMemPoolAttrReservedMemHigh: cudaMemPoolAttr

(value type = cuuint64_t) High watermark of backing memory allocated for the mempool since the last time it was reset. High watermark can only be reset to zero.

impl cudaMemPoolAttr

pub const cudaMemPoolAttrUsedMemCurrent: cudaMemPoolAttr

(value type = cuuint64_t) Amount of memory from the pool that is currently in use by the application.

impl cudaMemPoolAttr

pub const cudaMemPoolAttrUsedMemHigh: cudaMemPoolAttr

(value type = cuuint64_t) High watermark of the amount of memory from the pool that was in use by the application since the last time it was reset. High watermark can only be reset to zero.

Trait Implementations

impl Clone for cudaMemPoolAttr

fn clone(&self) -> cudaMemPoolAttr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for cudaMemPoolAttr

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

Formats the value using the given formatter.

impl Hash for cudaMemPoolAttr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for cudaMemPoolAttr

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