cuquantum.cutensornet.contraction_autotune_preference_get_attribute(intptr_t handle, intptr_t autotune_preference, int attr, intptr_t buf, size_t size_in_bytes)[source]

Gets attributes of autotune_preference.

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

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

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

  • buf (intptr_t) – On return, this buffer (of size size_in_bytes) holds the value that corresponds to attr within autotune_preference.

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


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