[ndnSIM] Same script, Same Random Seed, Different Machines, Get Different Simulation Result

[Alex Afanasyev]

Technically, you should be getting the same sequence of random values in NS-3... Just a couple of questions, by "same random seed" do you mean RngRun parameter?  Do you use only NS-3 provided random variables or rely also on system's rand (system's rand may give different results on different platforms)?
