I am a new user of Intel Vtune. I want to measure the L1 and L2 cache miss rate on intel Quad 4 Q6600 processor. The following formula is computing the L1 and L2 miss rate, am I right?
L1: L1D_CACHE_LD.I_STATE / L1D_CACHE_LD. MESI
L2: L2D_CACHE_LD.I_STATE / L2D_CACHE_LD. MESI
btw, I have another question about measuring the multithread application. I run two threads on the core0 and core1 of Q6600 which shared L2 cache. One thread is main thread, another is prefetch thread, How can I measue the impact of prefetch thread on the main thread? I mean how to evaluate the benefit ofprefetch thread?
hope for your responsing!
