Hi Alex,
You might want to have a look at SST.
For the rest, a xeon vs an i7 is probably a small improvement, but not much.
Surprisingly enough, we have seen that for workloads that scale nicely, running
with 8 simulated cores is as fast as 1 simulated core (the same "volume" of
events, but 1/8 of the time).
Give it a go and let us know the outcome.

Subject: [gem5-users] Using multiple CPUs to simulate a complex multi-core
system
Hello,
I am doing research work on multi-core interconnection systems that would be
used in 128+ core systems. I am planning on using gem5 to simulate the system,
but I am concerned that the simulation speed will be too slow on my current
computer. I am thinking of borrowing a multi-cpu system in order to speed up
the simulation, but I am wondering if there is a noticeable increase going to
something like a 16-core 3Ghz dual xeon computer from a 4.4 Ghz 4 core i7
processor. Also, is it possible to have gem5 running on a multi-node system
where each computer node is running an OS independently of each other?
Best regards,
Alex Tomala
