Hello,
Yes but i use TimingSimpleCPU.
kind regards,
Armel.

Hello,
I tried the patch and the problem persists.
As *Shehab Elsayed* said, the problem is more likely to arise when the
number of CPUs increases.
For me, the simulation ends with only *one CPU* and I have to set a
large *L2cache_size
(4MB)* for the simulation to end with *2 CPUs*. From *3 CPUs*
Hello,
Thank you for your reply. I will try the patch.
I think the command line is deterministic.
I realized that when I set the number of cpu to 1 or 2, the simulation runs
normally but from 3 it freezes in line *"brought up x cpu"*.
kind regards,
Armel.

Hmm... that's strange. I would expect that command line to be completely
deterministic.
However, Brandon just submitted a patch that fixes an undefined behavior
error for x86. It should be merged soon, but if you'd like to try it now
see https://gem5-review.googlesource.com/c/public/gem5/+/19568
Hello,
I use the command : *build/X86/gem5.opt configs/example/fs.py
--disk-image=$(pwd)/full-system-images/disks/linux-x86.img
--kernel=$(pwd)/full-system-images/binaries/x86_64-vmlinux-2.6.22.9.smp
--cpu-type=TimingSimpleCPU -n 4 --caches --l1i_size=8kB --l1d_size=8kB
--l2cache --l2_size=256kB*
Hi Armel,
It's unlikely the performance of the host machine. gem5 should be
deterministic, and the underlying host machine shouldn't make a difference.
Since you're seeing non-deterministic behavior, you should ask "what about
the simulation is changing?". Is it some configuration options (e.g.,
Hello everyone,
Sometimes when i launch full system simulation, the process seems to be
freezing at line "*Brought up 2 CPUs*" or at line "*Freeing unused kernel
memory: 248k freed*", and other times it launches well and show the m5
terminal. What can be the cause of the problem?? could it be rel
