Hi Andreas, Thanks for the confirmation. When I feed the statistics for small interval size (e.g. 1M cycles) to McPAT, I get high power usage (around 3 Watts per core) whereas for large interval size(e.g. 10M cycles), the power usage is low (around 0.6 Watts per core) which is a normal power usage . I do not know yet why McPAT generates high power usage for the small interval size. That's why I am wondering whether gem5 generates correct statistics for the small intervals. Do you have an idea?

Go ahead and give it a spin. Just make sure you've got plenty disk space.

I mean whether I can dump the statistics with an arbitrary size for the interval or there is a threshold for the interval size? Does gem5 dump stats correctly for intervals of small size? Thanks, Shervin
