Research direction

Start with examples/47_ampere_gemm_universal_streamk/ampere_gemm_universal_streamk.cu and review the reported half_t-to-bfloat16_t diff alongside the compilation-error screenshots. Compile the example with that substitution and identify the incompatibility; done means the example compiles successfully using bfloat16_t.
