Interface IDeviceMemoryManager

Namespace

NVMathNet.Memory

Assembly

NVMath.Net.dll

Allocates and frees GPU device memory for NVMathNet.DeviceBuffer`1. Implement this to plug in a pooling or externally managed allocator. Implementations must be thread-safe.

public interface IDeviceMemoryManager

Methods

Allocate(nuint)

Allocates sizeInBytes bytes of device memory.

nint Allocate(nuint sizeInBytes)

Parameters

sizeInBytes nuint

Requested size; always greater than zero.

Returns

nint

A device pointer that stays valid until passed to NVMathNet.Memory.IDeviceMemoryManager.Free(System.IntPtr).

Free(nint)

Releases memory previously returned by NVMathNet.Memory.IDeviceMemoryManager.Allocate(System.UIntPtr) on this manager. A pooling manager may hand the block out again immediately, so callers must make sure no queued GPU work still uses it (synchronise the stream first).

void Free(nint pointer)

Parameters

pointer nint

The device pointer to release.
