Dear gem5 team, I want to use gem5 to simulate a program to measure its execution time. My goal is to measure the execution time as close as possible to the real value, and that program is running in a heterogeneous platform, where other programs on other CPUs can affect the program execution time (memory, bus contention,...). I found this StackOverflow answer ( https://stackoverflow.com/a/56371006/9868917) states that it depends on whether the kernel interaction and system noise matter to us. So in general, will FS or SE mode gives more accurate execution time? And how the syscall emulated in SE mode compare to the real syscall in FS mode in term of speed? I mean, does the syscall in SE always has a fixed speed and usually faster than FS?
Best regards, Duc Anh
