CUDA pointer attributes

Fields

type_: cudaMemoryType

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

device: c_int

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).

devicePointer: *mut c_void

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

hostPointer: *mut c_void

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.
