How to visualize cache misses with pmc

[Nikola Knežević]

Hi,

During the tuning of my system, I was using pmc(3) to get various  
counters. Most important was the number of retired instructions, which  
helped me to discover some bottlenecks. However, I now need to get L2  
cache misses, which I do by running:
sudo pmcstat -S L2_LD -O /tmp/sample.out

and then run my module with its workload.

At the end, I have the output in /tmp/sample.out. However, I don't  
know how to get that data to anything useful, as gprof output is not  
very meaningful.

Any thoughts, hints, best practices?

Cheers,
Nikola
