Hi Abhishek, SMT is not something that is normally tested. I expect that this is a problem with se.py (and the 10s of other python files that it uses...). I suggest making a config script from scratch like in Learning gem5 so you know exactly what configuration you're running. You should be able to easily create your own config that has the parameters shown in your command line.
PS: The interface to gem5 is *not* command line parameters. The interface to gem5 is *python scripts*.
