Method Summary

Modifier and Type	Method and Description
int	device() The device against which the memory was allocated or registered.
cudaPointerAttributes	device(int setter)
Pointer	devicePointer() The address which may be dereferenced on the current device to access the memory or NULL if no such address exists.
cudaPointerAttributes	devicePointer(Pointer setter)
Pointer	hostPointer() The address which may be dereferenced on the host to access the memory or NULL if no such address exists.

Constructor Detail

cudaPointerAttributes

public cudaPointerAttributes()

Default native constructor.

cudaPointerAttributes

public cudaPointerAttributes(long size)

Native array allocator. Access with Pointer.position(long).

cudaPointerAttributes

public cudaPointerAttributes(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public cudaPointerAttributes position(long position)

Overrides:

position in class Pointer

memoryType

@Cast(value="cudaMemoryType")
 @Deprecated
public int memoryType()

Deprecated. The physical location of the memory, ::cudaMemoryTypeHost or ::cudaMemoryTypeDevice. Note that managed memory can return either ::cudaMemoryTypeDevice or ::cudaMemoryTypeHost regardless of it's physical location.

memoryType

public cudaPointerAttributes memoryType(int setter)

type

@Cast(value="cudaMemoryType")
public int type()

The type of memory - ::cudaMemoryTypeUnregistered, ::cudaMemoryTypeHost, ::cudaMemoryTypeDevice or ::cudaMemoryTypeManaged.

type

public cudaPointerAttributes type(int setter)

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 or::cudaMemoryTypeManaged 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).

device

public cudaPointerAttributes device(int setter)

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.

devicePointer

public cudaPointerAttributes devicePointer(Pointer setter)

hostPointer

public Pointer hostPointer()

The address which may be dereferenced on the host to access the memory or NULL if no such address exists. \note CUDA doesn't check if unregistered memory is allocated so this field may contain invalid pointer if an invalid pointer has been passed to CUDA.

hostPointer

public cudaPointerAttributes hostPointer(Pointer setter)

isManaged

@Deprecated
public int isManaged()

Deprecated. Indicates if this pointer points to managed memory

isManaged

public cudaPointerAttributes isManaged(int setter)
