I think you'll need to change the OS as it can move the threads around at any
time. Now if it's just the cores you want to move (because they're asymmetrical
in some way) you could make cpuN be some other CPU in the eyes of the kernel by
exchanging ThreadContexts between the CPU, but I'm not sur
Ali, thanks for the reply. I have a related question, hope you can give
some advice.
Instead of using setaffinity call, is it possible to hack the gem5
interface with the linux OS, so that I can assign any thread (with its
instruction workloads) to any cpu I want to? The reason to do this is
becaus
Where the instruction counts on the cores the same? If the application was
small enough the instruction and ilc might be dominated by the system booting.

I am running a parsec benchmark with 4 threads on 4 core Alpha FS machine,
I used "m5 pin" to bind all 4 threads to the first 2 cores. However, when I
checked the ipc in the stats, I saw all 4 cores have similar ipc. I am
expecting that only first 2 cores have reasonable ipc, and other cores
should
