Hi All,
I am a PhD at IBM Zurich. I am playing around with the new POWER9 servers. I am interested in plotting a roofline model for a given application, but I need to measure the traffic to and from the memory. Ideally, what I would like to measure is the traffic at the memory controller level. Do you know if this is possible using perf? If yes, which performance counters I should query to have an estimate on the memory traffic? Thanks for your time. Looking forward to hearing from you. Best regards, Lorenzo Chelini
