simpleGL could not be run from docker container in DGX2

[philipskokoh]

Hi,

I am trying to run simpleGL sample inside docker container running on DGX2 machine with CUDA version 10.2. However, I get this error.

May I know what is the possible cause of this error? I managed to compile the code by removing line 322 (about --threads) and removing '80 85' in line 301 and 302 in the Makefile. I am using this docker image nvcr.io/nvidia/pytorch:20.02-py3

# ./simpleGL 
simpleGL (VBO) starting...

GPU Device 0: "Volta" with compute capability 7.0

CUDA error at simpleGL.cu:421 code=304(cudaErrorOperatingSystem) "cudaGraphicsGLRegisterBuffer(vbo_res, *vbo, vbo_res_flags)" 
CUDA error at simpleGL.cu:433 code=400(cudaErrorInvalidResourceHandle) "cudaGraphicsUnregisterResource(vbo_res)"

Thanks!
