At compile time with flag -DQUDA_GPU_ARCH=sm_75 for turing architecture, warnings appear as shown below: ptxas warning : Value of threads per SM for entry ... is out of range. .minnctapersm will be ignored but with default -DQUDA_GPU_ARCH=sm_70 everything runs without warnings. Environment OS: Debian 10 Cmake 3.1.9 GCC 6.3.0 CUDA runtime: 10.2.89 Driver: 455.32 GPU 0: RTX 2080

What branch are you using? I don't see sm_75 available in CMakeLists.txt or anywhere else in the repo.
