Same problem with bandwidthTest. nvprof works with deviceQuery and
reports time spent in the various cuda query calls, but also reports "no
kernels profiled".
I did check the /dev/nvidia* permissions and they look fine to me, e.g.
crw-rw-rw. As I also mentioned, suid/guid on nvprof did not help
Martin, thanks for testing and for the link.
>From that link, it sounds like there is a known issue with cudaMemcpy2DToArray.
Would you try some of the samples from 1_Utilities, e.g. bandwdithTest, or even
deviceQuery and see if you get the same error?
At this stage, please keep nvidia-modprobe
I tried it, and the behavior is the same.
However, the thread http://devtalk.nvidia.com/default/topic/1025155
/-resolved-profiling-error-4168-999 suggests that this issue may be an
upstream bug, although the developer did not give details.
So maybe the Ubuntu package is all good, but we'll need t
Martin, I noticed your GPU has compute capability 6.1 and my tested GPUs were

There is no change running 'nvprof' immediately after 'sudo 'nvprof' or
vice versa. The former fails, the latter works. The same is true for
'nvvp' because of course 'nvvp' calls 'nvprof'. I ran 'nvprof' with
strace to look for some sort of write access to a /proc or /sys resource
