Error when running cuda example

[menesss]

Hi cuda experts,

i am learning to use cuda IPC to do my project. When i was running the example, this error appears:

"CUDA error at simpleIPC.cu:196 code=35(cudaErrorInsufficientDriver) “cudaGetDeviceCount(&devCount)”

I ran this example on 64-bit ubuntu 16.04. I already installed cuda-11.0.

anyone could help me figure out this issue?

You state that you installed CUDA version 11. Your installed driver supports CUDA only up to and including 10.1, per the output of nvidia-smi. Therefore your driver is insufficient to run this version of CUDA, as indicated by the error message.

Solution: Install the latest driver package available for your GPU.
