Also, will L1 data cache misses always report the cache misses for the cache closest to the CPU in the cache hierarchy? And if so, how can I monitor L2 cache misses and, for some machines, L3 cache misses? What I'm interested in is the L1 data miss rate, L2 miss rate, L3 miss rate. > For that you have to read about all the events available on your CPU. It is best to refer to the official documentation for family 10h cpus available at: http://support.amd.com/us/Processor_TechDocs/31116.pdf |
