warp.MemoryKind#

class warp.MemoryKind(*values)[source]#

Observed memory kind backing a Warp array.

This describes the memory class reported by Warp and CUDA pointer attributes. It does not describe current physical residency, migration state, synchronization state, or whether a specific device can access the array. Use can_access() for access checks.

Attributes

`UNKNOWN`	Memory kind that Warp cannot classify.
`HOST`	Default host memory.
`PINNED`	Pinned or CUDA-registered host memory.
`CUDA_DEVICE`	CUDA device memory that is not classified as managed or mempool memory.
`CUDA_MEMPOOL`	CUDA memory-pool allocation.
`CUDA_MANAGED`	CUDA managed-memory allocation.

UNKNOWN = 0#: Memory kind that Warp cannot classify.

HOST = 1#: Default host memory.

PINNED = 2#: Pinned or CUDA-registered host memory.

CUDA_DEVICE = 3#: CUDA device memory that is not classified as managed or mempool memory.

CUDA_MEMPOOL = 4#: CUDA memory-pool allocation.

CUDA_MANAGED = 5#: CUDA managed-memory allocation.
