cuquantum.bindings.cutensornet.workspace_compute_contraction_sizes(
intptr_t handle,
intptr_t network_desc,
intptr_t optimizer_info,
intptr_t work_desc,
)[source]#

Computes the workspace size needed to contract the tensor network using the provided contraction path.

Parameters:

  • handle (intptr_t) – Opaque handle holding cuTensorNet’s library context.

  • network_desc (intptr_t) – Describes the tensor network (i.e., its tensors and their connectivity).

  • optimizer_info (intptr_t) – Opaque structure.

  • work_desc (intptr_t) – The workspace descriptor in which the information is collected.
