warp.MemoryKind

class warp.MemoryKind(*values)

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.

__init__(*args, **kwds)

Methods

conjugate	Returns self, the complex conjugate of any int.
bit_length()	Number of bits necessary to represent self in binary.
bit_count()	Number of ones in the binary representation of the absolute value of self.
to_bytes([length, byteorder, signed])	Return an array of bytes representing an integer.
from_bytes(bytes[, byteorder, signed])
as_integer_ratio()	Return a pair of integers, whose ratio is equal to the original int.
is_integer()	Returns True.
__init__(*args, **kwds)

Attributes

real	the real part of a complex number
imag	the imaginary part of a complex number
numerator	the numerator of a rational number in lowest terms
denominator	the denominator of a rational number in lowest terms
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.
