Hi, Gabe, Thanks a lot for your answer. Now I am hoping someone can answer my second question as follows.
It seems that the two commands "--checkpoint-restore=XXX --at-instruction --warmup-insts=250000000 --max-inst=250000000" and "--checkpoint-restore=XXX --at-instruction --max-inst=250000000" produce the same simulation results, indicating that "-warmup-insts=250000000" does not take effect at all. I am wondering how I can warm up caches after recovering from a checkpoint??? However, using "--fast-forward" instead of "--checkpoint-restore" seems to work fine, but I 'd prefer to use ""--checkpoint-restore" to save time.
