Hi Peixin,

We have an updated version of the fat-tree model in CODES that supports oversubscription and we plan to contribute it back to CODES soon.

But the Stampede systems, which I simulated is with an oversubscription of 1.25:1, which means that each leaf switch with 36 ports is directly connected to 20 hosts and 16 ports in the core switch. So, does CODES support this configuration? And how should I modify the configuration file?
