[Gems-users] Number of instructions executed per core

[ubaid001@xxxxxxx]

Since there are no mutex locks, no processor is spinning. I have only my 
benchmark running on my Simics Target Machine (Serengeti). Is there a 
possiblity that the faulty core is running some other program rather than 
the art thread?
Also is there any way in Simics, to bind a thread to a particular processor?
So that i know for sure that all my processors are running the user thread.
