Hi，
Thanks, it really works for me.
What's the meaning of this variable “Runtime Dynamic”? Does it mean calculating
the average power of the component in the simulation process?
Another question is, Can I use this "runtime dynamic" to measure different
programs' performance ?

Hi,
The input which you are feeding to McPAT is not correct, that is why you are
getting inf as runtime dynamic. Compare your template with sample inputs came
with McPAT. Most probably some values specified in your template-xeon will be
stats.system.cpu.xxx. that you have to change to stats.system.cpu0.xxx. if you
are running multicore simulation cpu tag wont be there. There will be multiple
statistics corresponds to different cores in the format cpu0, cpu1,
cpu2...etc.. change those in template.
eg :
stats.system.cpu.numCycles need to change to stats.system.cpu0.numCycles
Read the warnings coming during gem5 output to McPAT input conversion. You can
see warnings related with these tags..

Hi，Midhun P
Thanks for your answer.
But I want to know why the value of runtime dynamic is inf, rather than a
specific value?
And my goal is to measure the energy consumption of different programs with the
same configuration in gem5,, how can I do?

Hi,
Only runtime dynamic will be different for different programs. All other
metrics (area, leakage etc) are depends on system config, so on different
programs with same system configuration, you will get same value.

Hi，
I ran different programs on gem5's SE mode. “./build/X86/gem5.opt
configs/example/se.py -c /home/zzh/code/scale_pre_00 -o 5 -n 2
--mem-size=2048MB --caches --l2cache --l2_size 1MB --cpu-clock 1.46GHz
--cpu-type=detailed”
Then I used McPAT to analyze their power.I follow the URL of the method, with
the inside of the files——GEM5ToMcPAT.py、template-xeon.xml
https://bitbucket.org/dskhudia/gem5tomcpat/src
But I get the contents of the two power files actually exactly the same.
What's the problem with this? Or，power is not related to the running program?
Power is only related to the hardware structure of the simulation?
