I am new to Nsight and I tried to profile executions of ML models on Jetson Orin Nano. I loaded the profiling result to Nsight GUI with the result shown in this figure. What does the value 0-100% next to the highlighted process mean?
This is the expert view. What does 74% of cudaSteamSynchronize and 21.6% cudaLaunchKernel mean?
The 0-100% is the range of the Y axis for this row. Value that reach the top are 100%, values close to the bottom are close to 0%. For this specific row, it represents the CPU utilization (note how the data in this row is correlated with the overall CPU data in the CPU rows group).
The percentages in the statistics view represent the fraction of time spent per named API call, over the total time spent in all API calls in this view.
