Dear Choi, there seems to be a problem with your results. If you see the Runtime Dynamic results, it mentions that they are either inf or nan. This means that in the xml file that was produced from the python script, the runtime statistics have not been written properly. As such McPAT does not compute the dynamic power consumption based on the runtime statistics produced by the gem5 simulation. It only computes a maximum power draw (something like a TDP value instead of a power value related to the program that you are actually running).
To correct this error you need to check the stats.txt file and the python script to see whether the version of gem5 that you are using somehow has modified the syntax or structure of the stats.txt file and therefore you need to account for these changes when you parse it with the python script.
