Description

Describe the bug
Only Volta GPUs are allowed to run the example.
https://github.com/NVIDIA/cutlass/blob/e1976daacc7b030ba672217eb5d96f5a663df4ab/examples/06_splitK_gemm/splitk_gemm.cu#L188-L189

Steps/Code to reproduce bug
Run the compiled program on a machine with compute capability >= 80.

Expected behavior
The program should work on Volta and later GPUs.

Additional context
I have locally tested that this could work on 89.

Research direction

Start in examples/06_splitK_gemm/splitk_gemm.cu at lines 188-189 and inspect the GPU capability check. Run the compiled example on a Volta GPU and on a machine with compute capability >= 80, including the reported 89 case. Done means the example works on Volta and later GPUs.
