cupy.cuda.ManagedMemory¶
- class cupy.cuda.ManagedMemory(size_t size)[source]¶
Managed memory (Unified memory) allocation on a CUDA device.
This class provides an RAII interface of the CUDA managed memory allocation.
- Parameters
size (int) – Size of the memory allocation in bytes.

dev (cupy.cuda.Device) – Device to apply the advice for.
- prefetch(self, stream)¶
(experimental) Prefetch memory.
- Parameters
stream (cupy.cuda.Stream) – CUDA stream.
