Research direction
Start with include/cutlass/conv/device/implicit_gemm_convolution.h and inspect how split-K support is conditioned on group count. Trace the surrounding convolution configuration to determine whether the restriction is performance-related; done means providing a maintainer-confirmed rationale, ideally with any relevant constraints documented.
