The output shapes of the
fusedLayerNormpluginfor nvFP4 are mismatched. This pollutes the barrier buffer for the one-shot allreduce kernel, which causes the hanging issue.This can also be the root cause of the accuracy issue as @zihaok recently mentioned. Because other data buffers are also messed up due to the out-of-range memory write.
