cuda.bindings._v2.driver.memcpy_peer( uint64_t dst_device, intptr_t dst_context, uint64_t src_device, intptr_t src_context, size_t byte_count, )#

Copies device memory between two contexts.

Copies from device memory in one context to device memory in another context. dst_device is the base device pointer of the destination memory and dst_context is the destination context. src_device is the base device pointer of the source memory and src_context is the source pointer. byte_count specifies the number of bytes to copy.

Parameters:

dst_device (uint64_t) – Destination device pointer.
dst_context (intptr_t) – Destination context.
src_device (uint64_t) – Source device pointer.
src_context (intptr_t) – Source context.
byte_count (size_t) – Size of memory copy in bytes.
