How to get the Cache Hit/Miss Rate?

[karenlenska]

Hi :)

I am not sure if i am in the right forum. If not, my apologies. If you know a suitable forum please let me know. My query is:

Is there any system call / package which allows the user to get the value of the cache hit/Miss rate for any application execution?
A second question, does the processor contain a register which is incremented on each cache hit? if not how the cache hit rate is concluded?

Thanks :)

You need to use a profiler to track performance counters.

What OS are you using? VTune is available for Linux or Windows. Also available for linux are oprofile, perfsuite.
