Hi Abdul, What do you mean by certain architecture? As you may know, CommMonitor is connected between two ports and so it (reliably and accurately) measures the latency and bandwidth statistics of requests between those two ports. I you want to measure these as seen by the application, you could connect the CommMonitor between the core and L1 data cache ports. If you are looking for characterizing, that is things like maximum bandwidth and static latency (ie round trip latency per single request is in flight), then running lmbench benchmarks could be useful .

I am currently using CommMonitor. Is that reliable or is there any other method to measure accurately in gem5.
