I ran programme at ubuntu16.04 with cuda10.1, nvidia driver430.09 and GTX 1660Ti, but met an error ‘cudaSafeCall() Runtime API error 715: an illegal instruction was encountered’.
Then i found the meaning of error 715(cudaErrorIllegalInstruction) at https://docs.nvidia.com/cuda/cuda-runtime-api/group__CUDART__TYPES.html. I don’t know what it is.
Later i used cuda-gdb to debug my programme, it showed that ‘Thread received signal CUDA_EXCEPTION_4, Wrap Illegal Instruction’. Some errors occured during warp.
I found a solution at Arnold gpu doesnt work gives gpu error. - Autodesk Community. It means that some compatible problems between GTX1660 Ti and cuda10.1 or nvidia driver.
How to solve this 715 error at GTX1660Ti?
