[GitHub] [incubator-tvm] alec-anyvision opened a new issue #6631: Race Condition in Cuda SSD Multibox

   I may be missing something about the IR, but there seems to be a race condition in the following line. There is no guarantee that `temp_valid_count[tid * num_anchors + k - 1]` will be computed before `tid == 0` reaches this point. However, in practice this seems very unlikely. https://github.com/apache/incubator-tvm/blob/21002cd094c34716b1e07a63ed76f53dadd60e23/python/tvm/topi/cuda/ssd/multibox.py#L234
