gpumemoryview

class pylibcudf.gpumemoryview.gpumemoryview(obj)

Minimal representation of a memory buffer.

This class aspires to be a GPU equivalent of memoryview for any objects exposing a CUDA Array Interface. It will be expanded to encompass more memoryview functionality over time.

Methods

byte_slice(self, s)

Return a byte-range sub-view of this buffer.

byte_slice(self, s: slice) → gpumemoryview

Return a byte-range sub-view of this buffer.

Parameters:

sslice

Byte-based slice.

Returns:

gpumemoryview

A |u1 view of the requested byte range. The returned view holds a reference to the parent buffer, keeping it alive.

Raises:

TypeError

If s is not a slice.

ValueError

If the slice step is not 1. Out-of-range or reversed ranges return a zero-length view rather than raising.

size

gpumemoryview.size: int

Size of the memory region in bytes (Span protocol).

This is an alias for nbytes to satisfy the Span protocol.
