Are you trying to run SMT or 2 CPUs?
If you are trying to run two CPUs then you have to explicitly assign diff.
workloads in your se.py file.
I think O3 only checks other SMT threads before returning true on exit....
If so, check the exit() function in in simple_thread.hh and make sure the
one in src/cpu/o3/alpha/thread_context.hh resembles the same code...
