[codes-ross-users] Fat-tree configuration support oversubscription >1?

Hi there,

When I do research about fat-tree topology uisng CODES, the fat-tree.conf
shows that the topology is with an oversubscription of 1:1, which indicates
that all hosts may potentially communicate with arbitrary other hosts at
the full bandwidth of their network interface. 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?

Best Regards,
Peixin Qiao
