cuquantum.cutensornet.workspace_compute_contraction_sizes¶

cuquantum.cutensornet.workspace_compute_contraction_sizes(intptr_t handle, intptr_t desc_net, intptr_t optimizer_info, intptr_t work_desc)[source]¶

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

Parameters

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