cuquantum.bindings.cudensitymat.state_attach_component_storage¶

cuquantum.bindings.cudensitymat.state_attach_component_storage(intptr_t handle, intptr_t state, int32_t num_state_components, component_buffer, component_buffer_size)[source]¶

Attaches a user-owned GPU-accessible storage buffer for each component (tensor) constituting the quantum state representation (on the current process in multi-process runs).

Parameters

handle (intptr_t) – Library handle.
state (intptr_t) – Quantum state (or a batch of quantum states).
num_state_components (int32_t) – Number of components (tensors) in the quantum state representation (on the current process).
component_buffer (object) –
Pointers to user-owned GPU-accessible storage buffers for all components (tensors) constituting the quantum state representation (on the current process). It can be:
- an int as the pointer address to the array, or
- a Python sequence of intptr_t.
component_buffer_size (object) –
Sizes of the provded storage buffers for all components (tensors) constituting the quantum state representation (on the current process). It can be:
- an int as the pointer address to the array, or
- a Python sequence of size_t.
