[GitHub] [incubator-tvm] were commented on issue #5741: Upgrade AutoTensorCore as to a TIR Pass

were commented on issue #5741:
URL: https://github.com/apache/incubator-tvm/issues/5741#issuecomment-640097428


   #5498 Kind of related to this one.
   The current TensorCore code generation is tricky --- since we have no fundamental wrap reduction support in TVM, generating TensorCore code inevitably messes up the thread bind. No threadIdxwas bound to a reduce axis before, but we inevitably need a threadIdx for that reduce axis. 
   
   Is it possible to somehow represent the warp wise reduce in the schedule, and then the TIR analyzer and rewriter can detect this opportunity of matching TensorCore.
