Hi,

What versions of CUDA driver & toolkit and nvprof are used? Output of nvidia-smi and “nvprof -V” would provide these details. Did you try the latest available CUDA toolkit version 12.2 Update 1? It can be downloaded from CUDA Toolkit 12.1 Update 1 Downloads | NVIDIA Developer.

I assume your system allows collection of counters/metrics based on the output “Replaying kernel …” but it is worth checking if you have permissions to collect GPU performance counters on the system. Web page NVIDIA Development Tools Solutions - ERR_NVGPUCTRPERM: Permission issue with Performance Counters | NVIDIA Developer provide details about the permission issue and how to enable access to counters on different platforms.

Hi,

This is a permission issue with GPU performance counters. NVIDIA Control Panel can be used to to manage the GPU Performance Counters access. Please follow steps on the page NVIDIA Development Tools Solutions - ERR_NVGPUCTRPERM: Permission issue with Performance Counters | NVIDIA Developer

I hope this would resolve the issue for you. Please let us know if you need any help.
