Hi, I am trying to run some benchmark on ARM full system simulation. Already use AtomicSimpleCPU to do the bootup and everything to speed up warmup, but still, ROI is few seconds of machine time, which takes up to few days to simulate. Also, for statistical confidence reasons, repeated run with same configs is wanted. With knowing that gem5 is deterministic, just re-restore with the same checkpoints will just give me same results. I want to launch multiple (for example 10) copies of same gem5 commands. Is there anyway in gem5, which allows insetting randomization between runs? For instance, can I somehow change the random seed in the full system, but after restoring from the same checkpoint? Or, I will have to just generate different checkpoints.
Any suggestions/help is appreciated! Best, Heng
