Hi everyone, I am puzzled as to why I cannot get Nsight Systems to work properly. It’s my first time using the profiler and posting here, so excuse me if the question turns out to be banal. I would be very glad if I could get some help. I am trying to use nsys to analyze my code, however, it shows…

Sorry, I haven’t found it yet

Hi, Have you managed to solve this?

It also happens to me. I am running on wsl2 with CUDA-12.1 [image]

The CUDA trace is generated only when the code uses unified memory, other traces are skipped, [image]

It looks like CUDA running in wsl2 still cannot be profiled. I got the results after switch to a linux workstation.

How did you get the result in Linux, I also encountered this issue under Linux, my cuda version is also 12.1

What driver are you using? I am on Driver Version: 530.30.02, CUDA Version: 12.1, NVIDIA Nsight Systems version 2023.1.2.43-32377213v0. My laptop system is ubuntu 22.04 LTS, a windows system running wsl2 won’t work for me. BTW, due to some conflicts, I recently re-installed all CUDA related software…

I am currently using 530.41.03 CUDA version: cuda_12.1.r12.1 and we share the same version of Nsight system on Arch Linux. Seems like we share pretty similar software equipment, so it might be caused by my CUDA program itself. Thanks a lot!

I am having this problem too. In my paid course online Jupyter notebook I can get output like CUDA API Statistics: Time(%) Total Time (ns) Num Calls Average Minimum Maximum Name ------- --------------- --------- ------------ ---------- ---------- --------…

WSL2 doesn’t allow access to all these metrics. Try to run your code in a complete Linux environment.
