1.1 Simulator system components

Our simulator system includes these components:

1. a parallel emulator which emulates a low level machine API targeting an architecture like BlueGene;
2. a message driven programming language (Charm++) running on top of the emulator;
3. the Adaptive MPI (an implementation of MPI on top of Charm++) environment;
4. a parallel post-mortem mode simulator for performance prediction, including network simulation.
