General Exploration--LLC

Hi,

I would please like some help on the following. I am doing a general exploration experiment on a small test case run on 24 cores on liniux. While in the "hardware issues view I see CPI being  over 1" and quite high on some particular threads(2.57etc)    LLC, Contested Acceess, Branch prediction and data sharing  shows to be  0. (As each thread is running on an array (size number of threads) I would expect to see data sharing actually.   Instead I see nothing, so no explanation why CPI is high. My run is quite small. Is it possible I am not hitting a hardware count limit and I see nothing? Is it possible for me to adjust this?

Thanks
