Getting Information on Relative Core Locations

[Gheibi__Sanaz]

Hi, 

We have a question and we really appreciate your valuable help. When we run Advance Hotspot Analysis on Vtune Amplifier, it shows which cores are being used by the threads.We want to see if for example core_0 and core_1 are physically close to each other and share an L2 cache. The same about other pairs of cores. Can we get such information? and how?

Thank you very much
