Nsys Does not Show the kernels output

[hossam.amer]

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 status -e

I am facing something similar to this forum link with vectorAdd

Nsight Systems does not collect CUDA events

This is an example ➜ CUDA_code nsys profile ./kernel_abc End of file ➜ CUDA_code nsys profile --trace=cuda,cublas ./kernel_abc Generating '/tmp/nsys-report-1d37.qdstrm' [1/1] [========================100%] report6.nsys-rep Generated: /home/alexandre/Code/CUDA_code/report6.nsys-rep ➜ CUDA_code nsys stats report6.nsys-rep Generating SQLite file report6.sqlite from report6.nsys-rep Exporting 9521 events: [===================================================100%] Using report6.sqlite for SQL…

I also updated the nsys version to the 2022 version using the following commands:

apt-get update && apt-get install -y nsight-systems-2022.4.2

Ran the profiling of vector add

/opt/nvidia/nsight-systems/2022.4.2/target-linux-x64/nsys profile --force-overwrite true -s none -t cuda vectorAdd

Again the same problem as the 2021 version with no specific kernel profile data shown. Vector add profile:
