I have an old s/w (code available), which was written for CUDA8 (and not compatible to work with CUDA9/10 without code changes). I had to change the GPU to RTX2080. Installed the 418.56 driver (long-term), OS is Ubuntu 16.04.
The code has a flag for JIT-compilation (for arch=compute_60). Compilation passes successfully, but hangs on the first cuda system call with :
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Is there anything I can do to make it running with new driver and the old CUDA 8.0? Maybe there is any “middle” driver version which will recognize the RTX2080 and yet will work with CUDA8?
Or my only option is to fix this code, to make it suitable for CUDA10?
Thanks in advance for help!
