hi steve. i think there is effect because, every time i run simulation i check the config.ini file. In config.ini under workload there is simpoint value. when ever i run simulation i check config.ini to make sure what ever values i used in configuration file is used by m5 or not.
This is what i found in config.ini file and there is simpoint value in it, so i am thinking it is using simpoint value.
