FakeTitle1Scalability

Distributed simulation in ns-3 allows a user to run a singlesimulation in parallel on multiple processorsBy assigning a different rank to nodes and connecting these nodeswith point-to-point links simulator boundaries are createdSimulator boundaries divide Logical Processes (LPs) and each LPcan be executed by a different processorDistributed simulation in ns-3 offers solid performance gains in timeof execution for large topologies

Simulation on a HPC cluster at the US Mobile Network ModelingInstitute (2011)2- 176 cores 3 TB of memory- 360448000 simulated nodes- 41370452 packet receive events per second [wall-clock]
