Sounds good. I will use that component then. Looking at my current system (in the attached PDF) it seems like I have to connect the Comm Monitor to the CPU and to the the sequencer to get the results I want. A second question I have is if there is anyway for gem5 to output a graphical view of how the ruby memory system is structured. In the config.dot.pdf file they just have a component called Ruby, so it is a bit difficult to see how everything will be interconnected for debugging/presentation purposes. - Alex ________________________________ From: Andreas Hansson <[email protected]> To: Alex Tomala <[email protected]>; "[email protected]" <[email protected]> Sent: Sunday, September 15, 2013 11:10:00 AM Subject: Re: [gem5-users] How do statistics work Hi Alex, It's essentially an extension cord with a lot of stats coming out, so just connect one between the two ports (CPU and Ruby) for as many CPUs as you want, and the stats will be in the normal output.

That will give you a latency history amongst other things.

I am wondering if anybody here knows any resources that can help me. I am looking to test the average latency of memory accesses in multiple ruby memory systems, but there are no default statistics for that, so I assume that I have to make my own. - Alex -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
