cuquantum.bindings.cutensornet.contraction_optimizer_info_set_attribute(
intptr_t handle,
intptr_t optimizer_info,
int attr,
intptr_t buffer,
size_t size_in_bytes,
)[source]#

Sets attributes of optimizer_info.

Parameters:

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

  • optimizer_info (intptr_t) – Opaque structure that is accessed.

  • attr (ContractionOptimizerInfoAttribute) – Specifies the attribute that is requested.

  • buffer (intptr_t) – This buffer (of size size_in_bytes) determines the value to which attr will be set.

  • size_in_bytes (size_t) – Size of buffer (in bytes).

Note

To compute the attribute size, use the itemsize of the corresponding data type, which can be queried using get_contraction_optimizer_info_attribute_dtype().
