CUPTI_ERROR_INSUFFICIENT_PRIVILEGES in container

[yzs981130]

The default configuration on my OS and current directions in README may lead to a CUPTI_ERROR_INSUFFICIENT_PRIVILEGES when using CUPTI inside the container.

The example log is attached below:

/home/ubuntu/home/habitat/cpp/src/cuda/cupti_tracer.cpp:120: error: function cuptiActivityRegisterCallbacks(cuptiBufferRequested, cuptiBufferCompleted) failed with error CUPTI_ERROR_INSUFFICIENT_PRIVILEGES.

RuntimeError: CUPTI_ERROR_INSUFFICIENT_PRIVILEGES

My solution:
Adding options nvidia "NVreg_RestrictProfilingToAdminUsers=0" to /etc/modprobe.d/nvidia-kernel-common.conf
and reboot.

Thanks! I'm glad you got it working. I've updated the README to add a link to NVIDIA's documentation and this issue. cd3735b
