[Gems-users] Number of instructions executed per core

Subject: [Gems-users] Number of instructions executed per core

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.

Hi,

I had brought this issue earlier. I am running Spec Open MP benchmark (art)
on a 4 core CMP system (OPAL + RUBY).

But there seems to be a huge difference in the number of instructions executed between one processor and the rest. I know that there are no mutex locks in the code. Infact I load opal and ruby only from the parallel section of the program.

The one core either lags behind or leads the other processor. And this happens on every single simulation.

Can anyone shed more light on this?
