Hello
I am a new user of M5 so I am sorry if the following will sound trivial.
I want to do some full-system performance/power estimations so I am running the
PARSEC benchmarks in M5 (for performance measurements) and then pass the
results to McPAT (for power and area estimations). My problem is that I don't
know which ones of M5's stats to transfer to McPAT, in the sens that there are
many who appear to point to the same thing. Some examples:
system.switch_cpus1.commit.COM:count 146267 #
Number of instructions committed
system.switch_cpus1.commit.COM:committed_per_cycle::total 238806
# Number of insts commited each cycle
system.switch_cpus1.committedInsts 143430 #
Number of Instructions Simulated
sim_insts 118094785 #
Number of instructions simulated
(I should mention that if you add the system.switch_cpusX.committedInsts for
all CPUs you don't get the sim_insts)
I also find it a bit strange that if you add all the different types of
committed instructions that are reported, you don't end up with the
committed.COM:count value.
Does anyone has a better idea about (or some experience on working with) this
counters?
10x in advance
