create_contraction_plan#

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

DEPRECATED: Initializes a cutensornetContractionPlan_t.

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) – Opaque structure describing the workspace. At the creation of the contraction plan, only the workspace size is needed; the pointer to the workspace memory may be left null. If a device memory handler is set, work_desc can be set either to null (in which case the “recommended” workspace size is inferred, see CUTENSORNET_WORKSIZE_PREF_RECOMMENDED) or to a valid cutensornetWorkspaceDescriptor_t with the desired workspace size set and a null workspace pointer, see Memory Management API section.

Returns:

cuTensorNet’s contraction plan holds all the information required to perform the tensor contractions; to be precise, it initializes a cutensorContractionPlan_t for each tensor contraction that is required to contract the entire tensor network.

Return type:

intptr_t
