Class CudaDevicePointerBuffer

Namespace

DotCompute.Backends.CUDA.RingKernels

Assembly

DotCompute.Backends.CUDA.dll

Simple read-only wrapper for CUDA device memory pointers used by message queues.

Methods

CopyFromAsync<T>(ReadOnlyMemory<T>, long, CancellationToken)

Copies data from a source memory into this buffer.

public ValueTask CopyFromAsync<T>(ReadOnlyMemory<T> source, long offset = 0, CancellationToken cancellationToken = default) where T : unmanaged

Parameters

source ReadOnlyMemory<T>

The source memory to copy from.

offset long

The offset in bytes where to start copying.

cancellationToken CancellationToken

Cancellation token.

Returns

ValueTask

A task representing the copy operation.

Type Parameters

T

The element type.

CopyToAsync<T>(Memory<T>, long, CancellationToken)

Copies data from this buffer to a destination memory.

public ValueTask CopyToAsync<T>(Memory<T> destination, long offset = 0, CancellationToken cancellationToken = default) where T : unmanaged

Parameters

destination Memory<T>

The destination memory to copy to.

offset long

The offset in bytes where to start copying from.

cancellationToken CancellationToken

Cancellation token.

Returns

ValueTask

A task representing the copy operation.

Type Parameters

T

The element type.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

DisposeAsync()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources asynchronously.

public ValueTask DisposeAsync()

Returns

ValueTask

A task that represents the asynchronous dispose operation.
