cuquantum.bindings.custatevecEx.state_vector_get_resources_from_unstaged_sub_sv_slice_view( intptr_t state_vector, int32_t sub_sv_index, int32_t slice_index, ) → tuple[source]#

Get resources from unstaged sub state vector slice (read-only view).

Parameters:

state_vector (intptr_t) – The state vector descriptor.
sub_sv_index (int32_t) – Sub state vector index.
slice_index (int32_t) – Slice index.

Returns:

intptr_t: host memory pointer to the slice data (read-only view; accessible from the GPU).
int: memory placement of the slice (a MemoryPlacement value).
int32_t: device id associated with the slice.
intptr_t: CUDA stream associated with the slice.

Return type:

A 4-tuple containing
