======== Warning: This version of nvprof doesn't support the underlying device, GPU profiling skipped
======== Warning: nvprof is not supported on devices with compute capability 8.0 and higher.

So I suggest an update of using another profiler.

Why does the hello world example do nothing? This fact is mentioned in the tutorial, but no further explanation is given. This is extremely confusing; what is the point of even writing that code if it doesn't work?

Hi experts, I met the following issue when running tutorial01/solutions/vector_add.cu:

[heyliu@controller tutorial01]$ ./vector_add
vector_add: vector_add.cu:48: int main(): Assertion `fabs(output[i] - a[i] - b[i]) < 1e-6' failed.
Aborted (core dumped)

any idea here, thanks!
