我刚看到Ali回复了你，他还提到了应该看overall_mshr_miss_rate，你能不能问下这个是怎么计算的，是不是mshr miss占总的cache access数的比例。。。

But I have some trouble of understanding the stat results. I found that there are five different values in the stat for the dcache.overall_miss_rate. system.cpu.dcache.overall_miss_rate::switch_cpus.data 0.163675 # miss rate for overall accesses system.cpu.dcache.overall_miss_rate::cpu.data 0.333333 # miss rate for overall accesses system.cpu.dcache.overall_miss_rate::total 0.163678 # miss rate for overall accesses system.cpu.dcache.overall_miss_rate::switch_cpus.data 0.065822 # miss rate for overall accesses system.cpu.dcache.overall_miss_rate::total 0.065822 # miss rate for overall accesses What is the difference between them? Which one should I refer to as the overall miss rate? Why there are two entirely different total dcache.overall_miss_rate? Thanks, Si
