[GitHub] [tvm] zhuwenxi commented on issue #7246: [BUG][Tensorize] race condition when using "tvm.tir.call_packed()" in a parallel schedule.

   And by digging into TVM source code, I believe I've already root cause this bug.
   
   Short answer: the TIR generated for "@tvm.tir.call_packed()" is not thread-safe, thus causes a race condition in a multi-threads environment.
   
   For detail explanations, please see my analysis here: https://discuss.tvm.apache.org/t/tensorize-tensorize-couldnt-work-properly-with-parallel-schedule/8752
