> ACL implementation Hi @giuseros Thanks for the work. I fully understand your purpose and smoothy development path. As this schedule will be the default NHWC depthwise convolution, my opinion is we should try to achieve a good performance as far as we could achieve. Notably I don't mean we mush achieve like ACL ultimate performance then we could merge, optimization is not one-shot deal. But here I think we could enable auto tvm to help us to achieve better performance. I think it is worthy introducing into this pr. - This schedule will be applied for arm32 and arm64 both, we shouldn't only consider arm64. So auto tvm (`split`) could help us to avoid this issue. - Tuning knob of `compute_at` (especially `data_pad`) could help us solve `parallel-compute-locality` issue (we can not assume we only run kernel only in one single core). see more detail: http://people.csail.mit.edu/jrk/halide-pldi13.pdf Figure 2 I agree we should reduce tuning knob and improve tuning time experience, but if it could help us improve performance, I think we should introduce it in, otherwise we could avoid it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
