test_gpu fails on RTX 3090 with CUDA 11.1

[mdabek]

Thank you for the warp-transducer, I was successfully using it with previous CUDA versions and on older card (RTX 2080) and with previous Ubuntu 18.04. I am currently trying to change the setup and move to the following configuration:
HW: RTX 3090Ti
OS: Ubuntu 20.04
CUDA: 11.1

The first change I needed to make was to remove the compute_30, since it is not supported by Cuda 11.1. The code can be compiled and I am able to run test_gpu. However, the option_test in test_gpu fails.
Here is the output:

All the grads calculated by option_test are 0.
Is this known issue? How can it be debugged and solved?

Thank you!

Maybe you should use "compute_86" for RTX 3090

you are right!!!
thank you very much,
i use RTX 3080, install and uninstall nvcc and NVIDAI driver many times......
