Hello
You used both -s (standard switch) and --fast-forward flags. The -s flag forces
a cpu switch at the beginning of the simulation (Switch at instruction count:0)
and --fast-forward triggers another switch later in the execution (Switching
CPUS @ tick 5123120000). You can look into gem5/configs/common/Simulation.py to
see what events trigger these two flags and understand the messages you mention.
Hope this helps!
B.R.

Subject: [gem5-users] "starting simulation..." message in SE/detailed
Hi
In SE mode, I use "-d --fast-forward=100000 --maxinsts=1000 -s". In
the output however I see:
Switched CPUS @ tick 123120000
switching cpus
Switch at instruction count:0
info: Entering event queue @ 123120000. Starting simulation...
info: Increasing stack size by one page.
Switching CPUS @ tick 5123120000
Simulation ends instruction count:1000
info: Entering event queue @ 5123120000. Starting simulation...
switching cpus
**** REAL SIMULATION ****
info: Entering event queue @ 5123121000. Starting simulation...
Can someone explain why there are *three* starting simulation
messages? I expect *two* starting messages.
Sart fast forward
switch
start detailed simulation
Regards,
