Grid Sim notes

These are some notes/howtos I've written while using Grid Sim 4.1/4.2beta to do my research. They are my own insights, and may not be entirely correct :).

Null Pointer Exceptions in Routers

I had an issue where at the end of the simulation my routers had NPEs in their dequeue method. The events had no data, which was were the error came from.

This was caused by the simulation ending by Sim Java having no more events to process, and shutting things down, and NOT by my user exiting which is the correct way to do things.
