Thanks for your reply. I have already read this document. My wonder is that 
which work have done when different CPUs switch. If they just share the same 
event queue, the switch between TimingSimple CPU with Ruby loaded and 
AtomicSimple CPU could also happens.

Hi Yongbing,
 
If you are using Ruby as the memory system, you can NOT leverage the fast 
forwarding feature because Ruby doesn’t support it. Please refer to 
http://www.gem5.org/General_Memory_System for the comparison between classic 
and ruby memory system.

Subject: [gem5-users] How to enable fast forwarding when ruby module is loaded?
 
Hi,
 
         I want to enable fast forwarding when ruby module is loaded. In the 
implementation, switching cpu should be happened between AtomicSimpleCPU and 
TimingSimpleCPU (plus ruby enabled). However, their cache and memory 
organization are different. What should I do in order to achieve this?
 
 
         Thanks.
