help

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
