Hello,
I will take a look at SST later, but first I am currently figuring out the best
way to implement my project. It involves making a tree network topology (and a
regular 2d mesh topology) with special controllers in the caches. I am
wondering if I should make a whole new cache component, or base it off the
current one (though the current one doesn't seem to allow for a custom
controller when inheriting it). I am thinking of possibly using the ruby memory
system, but I am not sure if it could be used to simulate both of those systems
(I need to compare the two network topologies).
Best regards,
Alex Tomala

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
