[Gems-users] copy architectural state from a core to another

["shanshuchang" <shanshuchang@xxxxxxxxx>]

Hi all,

 

I have booted 4-core CMP system, each one has a thread binded onto it to run the SPLASH benchmark binaries(./barnes < input_4p.8192). After running for some cycles, I want to copy the architectual state from one core to another(For example, from core-0 to core-2) So it appears to me that the system has two redundant thread except PID and some device infomation. I have modified the RUBY code to bypass the supervisor memory access, so at this point I suppose the workload running of the two threads are just the same.

But how can I copy the architectual state from one core to another? Is it possibly implemented in simics+GEMS ?

Is there anyone who has done some similar work ?

 

 

Any help is appreciated.
