How to detect hot data?

Portrait de Community Admin


I am tuning a program on Itanium 2. I want a quick way to find out hot data. In other word, I want to sort the virtual addresses by the frequency in which they are read / written. It is best if the data access and instruction access can be distinguished. Can it be done by using VTune or any other performance analysis tool? I appreciaite for your help. Thanks.

Hi pzhang4:


Currently, the analyzer does not support this usage model or data analysis. I think there might be some investigative work in this area. If you would like to pursue this topic, please submit an issue at Intel Premier Support.
