The current meta-schedule uses a PostProc
RewriteUnboundBlockto auto-bind blocks to threads. However, it's a post proc, which means there are no search opportunities, and always splits withfactor=1024.This PR adds a new search rule called
AutoBindto do a similar thing to bind threads with sampled factors. Also with a corresponding mutator.After applying this rule, we get some positive perf results (on RTX-3080):
Element-wise: from 2.76 us to 2.48 us
Conv2d Winograd: from 29.45 us to 18.96 us (ansor 22.00 us)
Resnet18: from 0.591 ms to 0.531 ms (ansor 0.565 ms)
