Differences between simulating spec2017 in fs mode and se mode

Hi :)

I simulated SPEC2017 in SE mode and FS mode.

I created a checkpoint before the workload was executed through bootscript and after this checkpoint, I checked the log with the option of --debug-flags=ExecEnable,ExecUser for the simulation result in fs mode.

In the log, there was an instruction stream that was not present in SE mode.

The number of them was very high.

Is it possible that some other processes were simulated during the workload simulation due to features like context switching that occurs in the OS?
