Hi, I currently use pfmon to collect cache_miss_rate every 1M insns of parallel programs. Because my server only has 2 PMUs, so I have to run benchmark twice(once measure cache_references every 1M insns, twice cahce_misses every 1M insns) to get cache_miss_rate every 1M insns.
I use the same input , and my enviroment is relatively stable. The problem is most cache_miss_rate I got is >1. I think it's because of pfmon's sampling property. Can u tell me what's the problem, and how can I avoid/reduce such variability? Thanks. ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
