Hello Sheng,

Thanks for your reply.As far your suggestion I have simulated gems with
both 4 and 3 VNs.  With 4 (0,1,2,3) VNs, V_network_3 remained inactive
throughout the simulation and the average loads for last three 3 VCs (3
VCs/VNs) also resulted in 0 flits/cycle. However, with 3 VNs, all the
networks and VCs are utilized.
So can I conclude that that MOESI in gems 2.1.1 uses 3 virtual networks?


Thanks,
Monobrata
