autotune_transpose_id Function

private function autotune_transpose_id(self, comm, cart_comm, from, to, base_dtype, base_storage, transpose_name_id, a, b, forward_id, backward_id) result(elapsed_time)

Creates forward and backward transpose plans bases on source and target data distributing, executes them DTFFT_MEASURE_ITERS times ( 4 * DTFFT_MEASURE_ITERS iterations total )

Returns elapsed time for best plans selected

Type Bound
