Measuring read and write traffic between LLC and DRAM

Hi,

I am new to AMD hardware.

Currently, I am trying to measure the read and write count that is served by DRAM.  In the intel processor, I was able to count read and write from uncore counters (memory controller) using PAPI.

I am using Zen2 processors: MD EPYC 7402 24-Core Processor

Any pointer on the counter name or tool name would be great.

Thanks.

Hello @monil01 ,

Have you tried using our uProf tool for this?  Found here:  https://developer.amd.com/amd-uprof/

 

Or the Processor Programming Reference (PPR) would contain the registers: https://developer.amd.com/wp-content/resources/55803_B0_PUB_0_91.pdf
