i used debug-flags=RubyCache,
Actually , i need data for tracing data such as cache memory address, cpu number, Hit/Miss, and Write/ read? is that debug-flags=RubyCache correct or other flag?
Hi there.
I suppose 500GB is fine! I mean, recall that there are a lot of instructions (including LW and SW ones) being processed into full-system simulation, thus, large trace files are expected.
Did you think about simulating small synthetic workloads using system call? Or perhaps the TraficGen from gem5 (never used it)...
What about restore the simulation from some checkpoint, just to get a ROI?
Try that options. It could help also if you wrote what you want to do with that experiment.

Thanks a lot for your answing ,
By the way, how can setting or know the number of banks in cache memory plz?
I'm not sure about that.
However, take a look at "Options.py" to see if any option can do that (Memory options). Also, look at "DRAMCtrl.py", or some files at this folder. Perhaps you can find something on them!

I tried the same in SE mode. Even there the trace files are coming out to be very big. For example, I used the RubyNetwork flag for blackscholes application(PARSEC benchmark, input data size : simmedium). There my core dumped after the debug file crossed around 750GB size.
I actually only need the flit information from the debug file. How can I possibly do that?
