MLC to support CoD for Haswell-EP or -EX

I was wondering if there is a version of MLC (Memory Latency Check) utility that understands the CoD (Cluster on Die) snooping mode for the Haswell platform. 

On a 2 socket Haswell-PE system withh CoD enabled, numactl -H shows 4 memory domains and accounts correctly the cores associated with each, MLC however treats the same host as just a 2 memory domain system and the tests DO NOT DIFFERENTIATE between the two memory controllers (and domains) that are available on each socket. 

Thanks

Michael

Sorry, we don't have any plans to support CoD at this time. Meanwhile, you can look at using -m flag (for b/w) and -i and -c flag for latency measurements and get the data you are looking for. You can refer to the readme.pdf for more information on that or post a follow up question here and I will be glad to answer
