Hi there,

I'm sorry if this had been asked before, but what are the exact performance 
counters that you guys used for the paper? I want to replicate the results 
reported.

The reason that I ask is because there are different combinations of measuring 
the same parameter. For example, to measure the L2 miss rate, I can either use 
`l2_access` and `l2_hit`, or replace `l2_access` with `l1_miss`, or `l2_access` 
and `l3_access`, or any of the above in IBS mode. Worse yet, I found that the 
results can be quite conflicting.

I am using Intel VTune with an Intel Westmere processor (Xeon E7-4870), which I 
believe is of the same generation as the one you used.

Much thanks!
Tri
