Hi Mengyu, A new region of the stats.txt file is added every time "m5.stats.dump()". So, if you trace through the python config file that you're executing (configs/custom/fs_elastic.py), you should be able to find where all of the places are that this function is called.
Without going through the script, I can't tell you when the stats are being dumped. The 4 places you suggest are good places to start looking, though.
