Hmm this info might be available when you see the config file - am not entirely sure. Alternately, there should be a way to snoop the Msg going out of / in to the NIC and display the name of the controller. Note that the order in which you connect the controllers in the topology file is the order in which the NI IDs get created. For eg., if you were to use MOESI_hammer protocol with MeshDirCorners_XY.py for say a 8x8 mesh, NIs 0 to 63 correspond to cache controllers and NIs 64 to 67 correspond to directory controllers.

A follow up question : Where should I look if I want to identify the specific Controller connected to a NI. I would like to identify a NI's corresponding controller by a name and a number, e.g. CPCntrl0, L3Cntrl1 etc. Regards, Arun Mishra [https://ipmcdn.avast.com/images/icons/icon-envelope-tick-green-avg-v1.png]<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> On Thu, Apr 23, 2020 at 11:12 PM Krishna, Tushar <tus...@ece.gatech.edu<mailto:tus...@ece.gatech.edu>> wrote: Each controller creates one NI. Multiple NIs connect to the same router within the NoC. So you can collect controller specific network stats from the NI it is connected to.

I am asking this because I need to collect some controller specific network stats and I want to know if there is a way to separate out the stats based on the NI it is connected with. Otherwise, is there a better way of collecting per controller network stats ?
