Function cutensorCreatePlanPreference 

pub unsafe extern "C" fn cutensorCreatePlanPreference(
    handle: cutensorHandle_t,
    pref: *mut cutensorPlanPreference_t,
    algo: cutensorAlgo_t,
    jitMode: cutensorJitMode_t,
) -> cutensorStatus_t

Allocates the cutensorPlanPreference_t, enabling users to limit the applicable kernels for a given plan/operation.

Parameters

• handle: Opaque handle holding cuTENSOR’s library context.
• pref: Pointer to the structure holding the cutensorPlanPreference_t allocated by this function. See cutensorPlanPreference_t.
• algo: Allows users to select a specific algorithm. cutensorAlgo_t::CUTENSOR_ALGO_DEFAULT lets the heuristic choose the algorithm. Any value >= 0 selects a specific GEMM-like algorithm and deactivates the heuristic. If a specified algorithm is not supported cutensorStatus_t::CUTENSOR_STATUS_NOT_SUPPORTED is returned. See cutensorAlgo_t for additional choices.
• jitMode: Determines if cuTENSOR is allowed to use JIT-compiled kernels (leading to a longer plan-creation phase); see cutensorJitMode_t.
