description = "INT8 activations break on transformers because a handful of input channels carry values 20x larger than everything else. The fix that actually ships — LLM.int8(), Atom, and every outlier-aware W8A8 stack — is to split the contraction axis: the few high-magnitude channels stay bf16, all the rest go to int8 with per-token and per-channel scales, and the two partial products are summed. Run as two library calls it costs two extra full-size passes over the output; fused it is one mainloop with two operand types and one epilogue."

# Without it ncu exits with ERR_NVGPUCTRPERM. `nsys` works without any extra capability.
