[image] hossam.amer: nsys profile --force-overwrite true -s none -t cuda vectorAdd I want to update the thread with the following working trial for vector add profiling after I tried it on a different computer. That’s the output of Nvidia smi: [image] That’s the version of nsys: NVIDIA N…

Hi user27549, Can you share your NSYS-REP file (i.e. the collection results) with us so we can take a closer look at what is happening on your system?

test.nsys-rep (39.0 MB) Here you go - Please keep me posted

That’s a snapshot of the diagnostics: [image]

Hi hossam.amer, The trace-fork-before-exec switch is not entirely safe and it does not guarantee traces. If you are using the Python multiprocessing module, could switch to using spawn for the start method and avoid using the trace-fork-before-exec switch? from multiprocessing import set_start_met…

[image] rknight: upgrade to the 2022.4 nsys release Hi rknight, Thanks for getting back to me. Please note that I used the NVIDIA Nsight Systems 2021.5.1 for viewing the shared profile, but I still cannot see the kernel profile data. I ran the suggested simplified command while adding the …

I also tried the same nsys command with the vectorAdd Cuda 11.6 toolkit sample. I face the same problem. Please note the following: cat /proc/sys/kernel/perf_event_paranoid 3 Is this the issue? If yes, that file is readonly on my system, so I cannot edit it. But it is -1 when I run the nsys st…

Hi hossam.amer, The perf_event_paranoid level does not matter in this case. It only affects CPU profiling operations. Can you run the nvidia-smi command and post the results? Can you also collect and injection log? To collect an injection log, run the following command; /opt/nvidia/nsight-system…

Hi rknight, Please find the injection log file. nsys-ui.log (16.6 KB) Output of nvidia-smi: [image]

Can you do another experiment that can help us narrow down the issue? Please follow the README.md instructions to build and use a cuda injection library in the attached cuda-injection-library-linux.tar.gz file. When you run your application following the Use instructions, please capture an INJECTIO…

[image] hossam.amer: apt I found CUPTI in /usr/local/cuda/lib64, added to LD_LIBRARY_PATH, and compiled well. That’s how I run vector add now: CUDA_INJECTION64_PATH=/home/hossamamer/young/cuda-injection-library-linux INJECTION_LOG_FILE=/home/hossamamer/young/cuda-samples/Samples/0_Introduct…
