Field Detail

memoryType

public int memoryType

The physical location of the memory, ::cudaMemoryTypeHost or ::cudaMemoryTypeDevice.

device

public int device

The device against which the memory was allocated or registered. If the memory type is ::cudaMemoryTypeDevice then this identifies the device on which the memory referred physically resides. If the memory type is ::cudaMemoryTypeHost then this identifies the device which was current when the memory was allocated or registered (and if that device is deinitialized then this allocation will vanish with that device's state).

devicePointer

public Pointer devicePointer

The address which may be dereferenced on the current device to access the memory or NULL if no such address exists.

hostPointer

public Pointer hostPointer

The address which may be dereferenced on the host to access the memory or NULL if no such address exists.
