Hi Dean, The number of vnets that get traffic ultimately depend on the coherence protocol. When you ran Simics, the coherence protocol you built will determine how many vnets are active and what kinds of traffic they carry.
If you are using the GEMS network tester, the traffic injector code in Tester.C might be hard coded to only inject traffic in vnet 0. If I remember correctly, it injects both control (1-flit) and data (5-flit typically) packets. You can edit it if you want. If you are using the gem5 network tester, details of which can be found here (http://www.m5sim.org/Networktest), it will inject traffic in three of the vnets as the wiki explains. - Tushar On Apr 3, 2012, at 7:03 PM, Dean Michael Ancajas wrote: > Hi, > My question is regarding the garnet network only tester from this: > https://lists.cs.wisc.edu/archive/gems-users/2009-October/msg00030.shtml > > I have made it run but I am wondering if there is a special reason why only > the first virtual network is used.
