first of all, I would like to ask which version of ndnSIM you are using. I guess this presentation refers to the previous version of ndnSIM (i.e., ndnSIM 1.0).

One option is to try to run the simulations using MPI, a feature provided by NS-3. I have created an issue on redmine for that (Feature #2504):


However, this issue has not been resolved yet, so I cannot provide explicit instruction steps about that.
