L2 cache miss rate如何计算？

[wwangzhihang100]

我看vtune中定义的miss rate是
Please use VTune event ratio named "L2 Cache Miss Rate", that is, L2_LINES_IN.SELF.ANY / INST_RETIRED.ANY
我觉得这样计算出来的是hit rate呢。谢谢

肯定是L2 Miss Rate.可以查online help

在线帮助我看过了，但是根据系统结构量化分析方法教材上的算法，L2缓存的缺失率不是这样算的呀。

The global L2 miss rate is L2 miss number/Memory reference, the local L2 miss rate is L2 miss number /L2 reference. What do you think about the above definition? How to calculate the L2 cache miss rate according to the above formulor. I mean which event I should select to measure.

intel optimize 手册上对不同的架构都有说明。
