cuquantum.cutensornet.accessor_compute¶

cuquantum.cutensornet.accessor_compute(intptr_t handle, intptr_t accessor, projected_mode_values, intptr_t workspace, intptr_t amplitudes_tensor, intptr_t state_norm, intptr_t stream)[source]¶

Computes the tensor network state amplitudes.

Parameters

handle (intptr_t) – The library handle.
accessor (intptr_t) – The tensor network state accessor handle.
projected_mode_values –
A host array of values for the projected modes. It can be
- an int as the pointer address to the array
- a Python sequence of int
workspace (intptr_t) – The workspace descriptor.
amplitudes_tensor (intptr_t) – The pointer address (as Python int) for storing the computed amplitudes.
state_norm (intptr_t) – The pointer address (as Python int) for storing the 2-norm of the underlying state. If set to 0 (NULL pointer), the norm calculation will be ignored.
stream (intptr_t) – The CUDA stream handle (cudaStream_t as Python int).
