Hello,
I am running ARM FS mode sims on gem5 with DVFS enabled. Currently only
CPU frequency is being scaled dynamically.
Now if in a simulation run, I observe N frequencies of CPU, then
invoking McPAT (for post-processing) N times, each time with respective
stats/xml, is technically wrong since McPAT will optimize the circuit on
every invocation.
What I want to do is to decouple the circuit initialization phase from
power computation phase so that McPAT creates a circuit model on first
invocation, and I can then use the same circuit for computations for
next N-1 invocations.
I have been going through McPAT source code and this does not look like
a quick fix. I believe someone in the community would have tried
something similar. Is there an existing way of achieving this decoupling
of McPAT phases or some McPAT version that I can leverage? Otherwise,
could someone give some details about how to implement this?
Thanks
Lokesh.
