Large Scale Model SupportParallel Simulation (1)

• For more scalability: parallel simulation

• Problem with parallel simulation:

  • Optimizations required to achieve good parallel performance
  • Networking expert ? Parallel simulation expert

• GloMoSim/PARSEC:

  • Transparent mechanisms of parallel execution to GloMoSim users
    • Most of the parallel execution mechanisms are in the PARSEC runtime libraries
  • Localized parallel execution code
    • Part of channel model: no need for protocol developers to change or even to see
  • Protocol models do not have to be modified for parallel execution
    • GloMoSim APIs prevent users from using global variables
