cuquantum.bindings.custatevec.dist_index_bit_swap_scheduler_get_parameters( intptr_t handle, intptr_t scheduler, int32_t swap_batch_index, int32_t org_sub_sv_index, params=None, ) → SVSwapParameters[source]#

Get the data transfer parameters from the scheduler.

Parameters:

handle (intptr_t) – The library handle.
scheduler (intptr_t) – The scheduler descriptor.
swap_batch_index (int32_t) – The swap batch index for statevector swap parameters.
org_sub_sv_index (int32_t) – The index of the origin sub statevector.
params –
Optional. If set, it should be
- an int as the pointer address to the struct
- a numpy.ndarray of dtype sv_swap_parameters_dtype
- a SVSwapParameters
and the result would be written in-place. Additionally, if an int is passed, there is no return value.

Returns:

the data transfer parameters that can be consumed later by a data transfer worker.

Return type:

SVSwapParameters
