i am a student and use the INTEL VTUNE AMPLIFIER XE on Ubuntu 14.04.
BUT, I am not familiar with the INTEL VTUNE.
I would like to measure LLC hit rate on i7 6700 processor.
I got the formula
LLC hit rate = (MEM_LOAD_RETIRED.LLC_UNSHARED_HIT * 35) / (CPU_CLK_UNHALTED.THREAD * 100) from
But, I have some questions.
1) I figure out that i7 6700 (skylake) doesn't have "MEM_LOAD_RETIRED.LLC_UNSHARED_HIT"
from a document "Events for INTEL@Microarchitecture Code Name Skylake"
Which events should I use insted of them?
2) Could you recommend some documents for measurement of cache hit rate on i7 6700 processors?
3) From that formula, Is that LLC HIT RATE caused by CPU?
4) I am running an OPENCL application on I7 6700. Is there any way to calculate the LLC HIT RATE caused by INTEL integrated GPU?
